I don't know about you, but the thought of "retirement" makes me think of boredom. The way I look at it, if you're not growing, you're letting life slip by. Drink up every last drop of life and grow by experience, by mind and by spirit.
Retire? Oh, someday I might take it easier. I might not punch a time clock, but I intend to keep busy learning and doing.
This list of things to do when you're done being a professional electrician may be all tongue-in-cheek, but let it help you think outside the junction box. Who knows! You could be the next Colonel Sanders.
