What do you do in The Sims that you really need to stop doing, but keep coming back to?

Making new sims and doing nothing with them. For one reason or another I come up with some plot or backstory and think "ooh I have got to make a new sim for this!" despite I probably have plenty of candidates that are sitting around doing nothing. Then, I play the sim for a bit, and then get bored. And that sim gets tossed into the void, in favor of my more popular sims.

Im trying to curb this by simply editing existing generated sims. It works...sometimes.
