There seems to be some confusion amongst people who move from writing code for fun to writing code for money. Which is of course that they're not being paid to write code, but to solve problems. Writers and musicians usually don't get paid just to write or make music, they get paid to entertain. If you're confused about why you're being paid, you might start to think you're getting a raw deal.

Since I started writing software not because of any love for it, but to solve various problems I was having at the time, it's always sort of shocked me that some people manage to get so far into their careers without realizing what they're being paid for.

I quite enjoy it now, but rarely in the revel of pure creation. Usually it's from the satisfaction of a problem solved in a reasonable amount of time under well considered constraints.
