Last minute

When do we wait till the last minute to do things? Then are disappointed when they don't turn out very well? I have 7 minutes till class and have decided to try and write this. I'll make it work, but it wont be as good as it should be. So is the case in my life wherever I have work. There's always something I've frogoten and do right before class. This is one of em and now I g2g History awaits.
