Procrastination :/

Why is it that we procrastinate. For instance I should be working on homework but instead I'm on here writing a blog. I just don't get it, with everything that is going on in my busy life you would think that I wouldn't have time to even think about procrastinating, but then here I am doing it just like this.
This will likely be a short blog as I am also very tired (I've been able to sleep a lot better lately probably because I spend all my free time procrastinating and then rush to get homework done as I am about to fall asleep). I sound like a horrible person right now. My goal always seems to be procrastinate less, and often I make it about this far in the semester and then lose it and go back to my old ways. Right now I'm about to crash so I gotta go do a little homework, but I'll be back I'm sure.
