So far today I've learned how to download python, and now I'm trying to make bots that will rule the world.

Today I learned that in 3rd grade an opinion is a "feeling you have about something you like or dislike." Feelings and thoughts/ideas are not the same thing. Opinions are thoughts. I feel very strongly about this. ;) For the record I generally like my 3rd grader's teacher.

Has anyone booked a flight to CVG when they intended to go to CDG? This seems like an error that must have occurred more than zero times, sort of like the time I showed up for my flight at LGA only to discover that I was flying out of JFK that day.

Training Copilot to be my GL accountant right now. it's pretty cool. And it weirdly feels like talking to a real person about problems I'm having with a journal entry. Next step: create an agent and share it with my team so they can do month end without me.

There's an important consideration that can be missed in working capital management in manufacturing or distribution: Sometimes growth is more expensive than run-rate.

You still won the work. You're still growing, but your working capital cycle that is usually 60-90 days is now 180-360 days as you ramp up. Once the ramp-up happens, you catch up and the cash comes back. But these swings don't show up in averages.

I'll confess I didn't realize this is what was happening the first 3-4 times it happened to me, but now I'm acutely aware of the reality and it's changed how I plan and forecast, and how we acquire businesses.

We survived years with DeBlasio, despite the immigration crisis, the homelessness crisis, the crime crisis, and the affordability crisis. Adams was OK for 3 years. Now we can survive Mamdani for 3 years before we go back to real adults running the city.

Just heard from another source that we were in a manufacturing recession for half of 2023 and all of 2024. Anyone in manufacturing knows this. It still hasn't hit the normie news.

I’m an east coast supremacist but west coast beer is the only true beer. Pictured: flight of fresh hopped beer at the Portland Airport. No east coast tap room could come even close to this quality and variety. This is offered on every block in Portland. As available as pastrami on rye in NYC.

The IRS owes me $14,000. Can I put a lien on them or send angry letters threatening jail time? Of course not! Best case scenario I get a refund without interest some time in the next 12 months, while they continue to take my monthly and quarterly payments. In unrelated news, businesses I control have paid over a million dollars in tariffs this year, a tax that was never voted on by Congress. ...And people wonder why I'm a libertarian.

Kudos to Indian English. I just heard "prepone" for the first time and I love it. Obviously it would be the antonym of "postpone" and it fits the Latin root ("pre- ponere" -- put before)

This guy is right. 10 years ago we were doing “digital transformations” in finance functions and there wasn’t much cost savings because a good finance function isn’t expensive relative to the business it maintains. If your goal is to obsolete your AP team you have another thing coming (at least in the next 5 years). If your goal is to fraud-proof your AP team and make it easier to manage vendor relationships smartly, AI can probably help.
It’s hard to find balanced takes on what AI means for finance teams in the short term. Over on LinkedIn, people are fully losing their minds. My feed is filled with fantasies of CFOs firing their whole team after a heavy weekend of vibe coding. Let’s be clear: AI is going to transform the CFO's office. But not in the ways you’re reading about. Not yet. Like every tech wave before it, Amara’s Law will apply. We overestimate the short-term productivity impact and underestimate the long-term one. AI is right on cue. And this time, the curve may well be steeper. But that doesn’t make today’s hype any more helpful. You’re being told to fire half your team. Rebuild your stack from scratch. Learn to code like an engineer. For CFOs that is nonsense. Very little AI tech for CFOs is truly enterprise-ready yet. If the world’s best engineers - backed by billions in funding and full-stack AI teams - are still building, what makes you think you can crack it with two mugs of coffee and a 45-minute YouTube Replit tutorial? The idea that a CFO or their finance team should be building proprietary AI software isn’t just unrealistic... today it’s borderline reckless. You’re not a product org. You’re not a startup. You’re the steward of your company’s finances. Your job is to protect the business’s assets and grow shareholder value. To be clear, this advice is for established CFOs and senior finance leaders. If you’re early in your career, or you’re a current or aspiring CFOTech founder? You should absolutely be experimenting more aggressively. That’s a different playbook (and not one I should write.) But if you’re already in the seat. Running a finance team, managing cost pressure, tariff chaos, audit reform, and a volatile boardroom... your job is not to vibe-code your way through it. Now let’s talk about the “95% myth.” There’s this idea floating around that AI can do 95% of a finance task in five minutes - board packs, forecast models, strategy decks, you name it. But in finance, precision beats direction. Just because something looks 95% done doesn’t mean it is. Worse, it gives a false sense of confidence. You think you’re nearly there. You’re not. The final 5% is where all the risk lives. All the value. All the judgment. That’s the bit that matters most. CFOs aren’t paid for the first 95%. That’s the commodity layer. They’re paid for the last 5%, the sharp end of the decision. The edge. And the best-paid CFOs, are paid seven or even eight-figures ones for the final 0.1%. The part that only experience and real-world judgment can deliver. So if you shouldn’t be hacking your team to death with AI experiments, what should you be doing? Here’s the practical AI playbook for CFOs today as I see it: 1. Reframe where AI can actually help. It can’t write your board paper. But it can help you tighten it. It won’t build your model. But it can sanity check it. It won’t find your narrative. But it can pressure test it. 2. Don’t trust the “95%” myth. People say AI gets you 95% of the way there. But that’s an illusion. Just because something looks 95% done doesn’t mean it is. And in finance, that last 5% - the nuance, the judgment, the risk - is everything. It’s not the final touch. It’s the whole game. 3. Let the builders build. Take the demos. Work with tech vendors who live and breathe finance problems. Your job isn’t to build an AI-powered P2P system from scratch. It’s to pick the best one on the market and implement it well. We are a generation of CFOs scarred by horrendous tech implementations. But AI will make implementation and customization infinitely easier than we've seen before. 4. Get your data organized. AI loves structured data. The more your data is clean, consistent, and well-structured, in a proper data warehouse layer, the more AI-ready you actually are. Think integrity, granularity, metadata. That's what will unlock what comes next. 5. Experiment in low-stakes environments. Play where failure doesn't hurt. In my case, I built custom AI bots to help my kids with homework, tailored to their curriculum, learning preference, instructed to guide to the answer not give them the answer, etc. That’s stretched my thinking and showed me the art of the possible, more than any finance workflow. It’s where I’ve learned the most. You want cheap feedback loops, fast iterations, low risk. And for what it’s worth, here’s where I’ve seen AI be genuinely useful so far: - Editing comms: emails, specs, board packs - Sorting and prioritizing inboxes - Stress-testing story outlines and presentations - Surfacing directional insights from messy data - Scoring candidates against hiring criteria - Acting as a thinking partner when I need to challenge my own assumptions. So no, don’t fire your FP&A team and vibe-code a workflow replacement. Experiment, yes. But pick simple workflows. Low stakes. Clear feedback loops. Don’t eat the hyperbole. Keep one eye on AI, not both eyes and both hands. Your job is to run the business, not chase the unproven LinkedIn fever dreams. Keep your hands on the wheel. Stay curious. Stay skeptical. But most of all ... stay very f*cking crispy.

Wise words from an excellent dad.
If you are a dad to daughters listen carefully. If you find a hair tie anywhere, grab it, put it in your pocket, put it on your wrist. Very soon, a small person will need a hair tie and you, Dad, will have one. Eventually, every time she needs a hair tie she will come to you. Sometimes, when she does you can grab a hug from that little person. One thing leads to another, and don’t be surprised if you also learn to make pony tails, buns, and braids while she talks to you about what is on her mind.

I just assigned a new employee to make a presentation in 2 days to our plant leadership team. I wasn’t sure what the response would be, but she was thrilled! I love hiring people who make the whole team better. Brings new energy and excitement.

Embarrassed at how little endurance I have for a standing desk. How long will it take?
