motivation and control...?

what motivates us? or me? I'm sitting here not wanting to start on my homework which is coincidentally due tonight. but i can't seem to get started on it. so... what is it that will eventually get me going on my homework and finished? the fact that i want to go to bed and not have this hanging over my head the next time i see my teacher. it's funny that really it all just boils down to being too lazy to do things... in my case anyway, I'm just not in the mood or if it requires too much of what I'm not willing to do or give... why do we let ourselves get this bad... my body governs me and I'm not sure if I'm glad about that idea yet. i like to know I'm in control. but i guess i really never am i just have a figment of it.
