Reading, p181, about this Jarvis, this quote resonates,
" It’s hard to detail the full list of things Jarvis has worked on in recent years, as his various ideas leaving behind a trail of broken URLs and out-of-date websites: which is, of course, exactly what you’d expect from someone who isn’t trying to build the next Microsoft but is instead pursuing just enough work to engage his curiosity while supporting his slow, inexpensive life-style."
And reminds me of Pieter Levels too. The entrepreneurial mindset scaled up and scaled down, trying things out relentlessly until something sticks. Risks, but they energize you to keep going to the next thing with small bits of progress in between.
