I really dont like still lifes, but i have to do one for an audition?

This ignment is testing your ability to concentrate and complete a project - apparently that's what you would be doing in your new school. If you try to stop thinking about it while you're doing it, that would help. In other words, if you're thinking to yourself, "OMG, I can't do this any more!" you'll hate every minute of it. Instead, focus on trying to do the best job you can possibly do and you'll get through it faster and the result will be much better.
