I wrote a blog post, that ended up Hacker News, called: "What's happening with founders over 40?" I got a lot of comments and reactions to the piece, so I thought I'd respond to those here.
"At 44, I don't feel like I still have the raw horsepower in terms of creative mental energy that I did 20 years ago."
"It's like gradually and then sudden. And there's actually research that shows that aging might happen in these bursts."
"A 50 year old entrepreneur is nearly twice as likely to have a runaway success as a 30 year old."
"Nothing sticks. I have to clear my schedule, concentrate, take supplements, stay up late, and take copious notes just to make a bit of progress on anything."
"You can't have the same kind of energy or creative firepower forever. I did that. I can't do that anymore, but I can do other things now."
