Self sabotage

I keep setting goals for myself that I'm just not able or motivated enough to actually follow through with. For example: It's past midnight and I have to get up tomorrow for work. I'm tired, yet I keep letting myself fiddle around on this stupid computer of mine. I've also set goals for studying for the VTS test as well as an exercise plan. This is short blog because I need to go to bed. I just wanted to put out there that I really need to figure how best to deal with my own self sabotage. I hope I figure it out soon.
