I started as a creative person, programming. I realized I had to go back to that to be happy. So I typed an email to my cofounders on the spot. Three days later, I was out of there.
I was fortunate to remain good friends with most of my cofounders and key employees. I've had a blast in the succeeding years - making a better income most years and getting to do things I enjoy. Having time for a great wife and kids makes it even better.
It was the best decision I ever made.
