I spend a lot of time fixing things, for myself and others. (Computers, electrical, plumbing, etc). While I learn a lot, I wonder sometimes if it would be better to pay a professional and do something else for which I am more 'valuable'. Do you do the same, and do you find it worthwhile?
Confucius once said "choose a job you love, and you will never have to work a day in your life."
If you love what you do, the rest will follow.
