Dream come true! I am a published author! A dream that took WORK. Months of research and writing to be specific. The author copies of my very first book, "The Martech Handbook" have arrived! And they are beautiful. Please pre-order now wherever books are sold!

The most important skill in life isn’t predicting the future. It’s adapting to the one you didn’t expect.

Your iPhone is dying by 2 PM every day. It's not the battery. It's 14 settings Apple turned ON by default that are silently draining it in the background. I changed all of them and gained 4 hours of daily battery life. Steal them

Just gave a talk to 2,000 people today. 10 raised their hands; they've used agentic AI. 20% (maybe) knew what Claude was. You are earlier than you think you are... still.

Personally, I'd like to see more real intelligence rather than more artificial intelligence.

If you get surprised by a layoff: - Leave graciously - Negotiate your package - Slow down your burn rate - Allow yourself time to reflect - Build a systematic search process - Take the epic trip you've been putting off Use action to relieve your anxiety.

You can tell someone’s smart by how well they simplify things, not complicate them.
