I'm almost always in a position where I could say I'm too busy to work on something. I like it because the jobs that I really want to do, I'll find the time to do. But for the ones I don't want to do, I can either say I'm too busy or else bid 4x my normal rate. If they want me for 4x, I'll make the time.
