Good to see that you're doing something now mostly for the joy of it rather than the daily grind. My dad was the chief executive of a major US insurance company-spent twenty years there working his way up from an entry actuarial position. He was getting increasingly unsatisfied with the job and the strain it put on family with his long work hours and increasing travel demands. In his last 18 months there, he began quietly looking at what he might do to ensure our financial security while keeping a hand in the insurance business but only as a consultant. He learned the consulting business from mom as she had a successful small environmental consulting business. At age 50, he dropped the bomb on the company-giving six months notice to the board of directors. They were naturally totally unprepared for this, fully expecting him to retire at age 65 as his predecessor did. It's been something like ten years since he left the company and he's never regretted it. After the retirement, he was able to spend so much more time with us and we really saw what we had missed out on.
One thing I have learned from this is that life is too short to waste doing a job that you don't enjoy. I work in my profession because I largely enjoy it-money is not the overall motivating factor.
