Formulating A Plan

I don't have any problems with the morning in doing some things that I set out myself to do, but at night I'm just about ready to be beat. I think before I get really sleepy and not in the mood for doing anything because that's how I seem to always end up at night, I should pretty much take care of it before I get really sleepy or at least have a little will-power to set my personal time aside and get it accomplished.
