A reminder from Atomic Habits by James Clear:
“It doesn't make sense to continue wanting something if you're not willing to do what it takes to get it. If you don't want to live the lifestyle, then release yourself from the desire. To crave the result but not the process is to guarantee disappointment.”

This week the most advanced AI model on the planet got switched off by a foreign government. British researchers were studying it. British companies were testing it. British hospitals were piloting it. Not any more.
This isn't an AI story. It's the story of every industry we used to lead.
Britain has some of the best AI talent in the world. DeepMind was built here. Our AI Safety Institute writes the rules other countries follow. We have the researchers, the universities, the standards.
What we don't have is the power stations to run the data centres, the planning system to build them, or the industrial base to make the chips. So the work happens here and the value lands somewhere else. We invent. Others build. Others decide. Then we read about it on Saturday morning.
Same story as the kit our soldiers don't have. Same story as the factories we used to.
I spent nine months in government making this argument inside the room. I'll make it louder from outside.

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.
The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
Access to all other Claude models is not affected.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

Every single person who still cringes at the memory of trying to bullshit their way through an interview or exam question: today, the slate is wiped clean. Set down your burden of shame. Nothing - nothing, I say - could touch this.

I am half way through the new Market Wizards book, and few things stand out insane work ethics, self leadership, self belief bordering on delusion and ability to go deep once they found setup ideas.

Update on The 17.6 Year Cycle — 5 years later
Back in 2021, I showed how real returns were barely positive during the 2000–2018 secular bear market.
(Remember that my book was published in 2013, this refers to the update of my X post below.)
Fast forward to 2026:
The current secular bull market (2018–2035) has delivered strong nominal and real gains, exactly as the cycle predicted.
Here’s the updated table with performance through April 2026 (nominal & inflation-adjusted annual returns, excluding dividends):
Key takeaway:
• Secular bear phases (like 2000–2018) → low or negative real returns.
• Secular bull phases (like now) → compounding works powerfully again.
This is precisely why my algorithmic long/short S&P 500 system stays long-biased in favorable cycle phases and can shift defensive when needed.
The cycle never sleeps.

The 17.6 Year Stock Market Cycle is real - and it remains one of the most powerful tools for timing the S&P 500.
Real returns in this secular bull phase are playing out exactly as the cycle predicted. Below is the updated data through May 2026.
The current secular bull (2018–2035) has delivered strong nominal and real gains — right on schedule. We’re not at extremes yet. I’m not buying the “2026 market top” narrative.
Key takeaway:
• Secular bear phases → low or negative real returns. Compounding struggles.
• Secular bull phases → high real returns. Compounding works powerfully again.
This is exactly why my algorithmic long/short S&P 500 system stays long-biased in favourable cycle environments.
How are you positioned right now?

£12.5k now, then compounded in the property market for 40 years is worth losing a years state pension for!

Take it whilst you can cause we’re not getting a state pension

$BTC WILL DROP TO $50K IN JUNE
BTC closing second Bear Flag in this cycle
$65K is historically strong support, but the data shows how fragile it is
RSI at 37 with room to fall, ETF outflows deepening, and selling volume still heavy - nothing here says bottom
I called the exact top of this bull trap
Follow to not miss when I call the bottom
May 2
$BTC Always closing its CME gaps
Once this happens, $10 billion in short positions will be liquidated
Retail will start believing in the rally again
This is where the Bull Trap will snap shut

This is an issue that’s about more than money. I think people buy brand new cars because they’ve had bangers and they go wrong and fixing them is expensive. With a PCP you drive a nice car and you know your costs.
I also think it’s partly status. People want to feel that they are making progress and a new car makes you feel good.
I find that those who can easily afford to buy a new car are the least likely to do so.
May 31
Over 85% of new cars in the UK are bought on finance, mostly PCP
You are paying £400 a month to borrow a depreciating liability that loses 60% of its value in the first 3 years
If you invested that £400 a month into a basic index fund instead of renting a status symbol, you would have over £300,000 in 20 years
You are trading a multi-million-pound retirement for a mid-range German saloon

That's not overly aggressive either Kerry. Roughly doubling over the next 8 years in real terms.
