First, realize that you don't have to go to university now. It can happen later.

Second, what do you really want to do with your life. You say you want to be a creative, do you know what the day to day life would look like? If not, find out. You may love it; you may hate it, but find out first.

There's a lot to be said for following your passions, just realize that money typically doesn't tag along.
