    I’m currently at the Global Entrepreneurship Congress 2025 in Indianapolis. Yesterday, at the end of the day, I spent several hours at High Alpha hanging out with my friends and then doing a Give First: The Power of Mentorship book event with them and about 150 people. One of the questions during the book talk was around mental health and entrepreneurship.

    A long time ago, in a galaxy far, far away, I was a CTO of a large, fast-growing public company. Well, I was a Quasi CTO in the same way the United States and the First French Republic had a Quasi War between 1798 and 1800 (basically, sort of a war; sort of a CTO … but not really.)As I rediscover my second love (my first love is Amy), I’ve relied on several mentors to help guide me. One of them is Michael Natkin, who has been helping me with Cursor in the background at a few key moments.

    This played out on @bfeld on X, and I thought it was fun enough to replay it here for anyone who is struggling to get their minds around vibe coding and current AI tooling. If you are receiving this via email and the tweets/X’s aren’t showing, click through to the website as I’m still struggling to get Mailchimp working well after my hibernation. Perhaps it’s time to switch everything to WordPress…It started with this tweet (yes, they are still tweets to me).

    As a voracious reader, I love a good table of contents (TOC) as the roadmap to a book. While fiction is often structured as Chapter 1, Chapter 2, Chapter 3, … Chapter N, some of the best fiction writers are creative with their TOC. Any non-fiction author who doesn’t provide a detailed table of contents TOC is missing an opportunity to help the reader understand the book’s flow before they begin reading it. Below is the Give First: The Power of Mentorship TOC.

    I did a talk with a private community of 100 GPs and investors in venture capital called Aces last week. It’s an off-the-record, confidential group organized by a few people, including Max Beaumont, who said I could mention him in this post. Max sent me the following summary. I asked him if I could post it, and he said yes. Thank you again for taking the time to join us yesterday, and for staying well past the scheduled end.. I could tell how meaningful the conversation was for those who stayed..

I spent some time thinking (and writing) about a set of things that followed a tweet from a few days ago about something I had enjoyed reading on vibe coding / AI coding tools. https://t.co/wYC320R4PS

I'll be at Composition Shop in Longmont all day tomorrow, the only place on planet Earth where physical copies of my new book, Give First: The Power of Mentorship, will be for sale until its release on June 24. https://t.co/9YQpbzknRC

While I'm talking about Give First these days, I'm changing it up some to keep myself from getting bored of myself. https://t.co/or30YCRiV9
