Too Many Irons

The phrase "too many irons in the fire" is based on a simple fact: if a blacksmith tries to heat too much material at once, the result will be of inferior quality because the metal is not being worked at the correct temperature. Even though I know better, I still fall into the trap of trying to do too much. I really need to re-evaluate the priorities of the stuff I'm working on, otherwise the results will definitely be inferior.
