A company I worked back in the dot com boom days... one of the sysadmins was a bit on the grumpy side. He had been there from the start and had some nice options to be able to cash out on and try something. So he cashed out and pursued his dream of being a chef - finished up some certificates and such... and became a chef.

About a year later, he came back to working as a sysadmin no where near as grumpy. He got a job as a chef... and realized that as much fun as the cooking is he really didn't like being a chef.
