I made a big mistake years ago and turned my hobby duck carving into a business, it got to where if I took a week of vacation I had to spend it carving ducks to try to catch up with the demand. One day I thought "this sucks" put my tools down and never carved another duck.
When I started making bows I only did it when wanted to, I was in it for the work which I loved, not the money. I had the money angle covered from 30 years of working in a power plant, I worked between 500 and 900 hours of overtime a year and was able to retire at 52 at the same money I made while working, I took saving for retirement VERY seriously.
