Not the OP, but the coding I find additive is not the coding I get paid for. E.g. playing around with a new language or framework because its fun.
These days I get an infinite amount of pleasure from chopping onions, carefully cooking them until they caramelize, salting/spicing them ever so slightly, and watching the smiles on my friends faces. It's a definite and immediate payoff, and a visceral one at that :)
