I avoid billing and bookkeeping as long as I can.  It’s not that the work is hard, it’s just not my fave thing to do.  I let it loom larger than life inside my head.  So when the deadline is approaching, what I have to do is start psyching myself up a few days ahead of time, changing my self talk from “I don’t wanna do it!” to  “It will feel good to whip thru the billing Friday and have it behind me.”  I tell myself that over and over a few times a day for days beforehand.  Every time the thought comes up that, “oh phooey I can’t have fun until after I do the billing,” I remind myself it’s just a four hour job if I stay focused.  It’s a guilt-ridden four day job if I play on Facebook at the same time.   And for now, it’s Friday and the billing and bookkeeping is done.  Everyone wins!
