Try and try again. Most of the people on here who didn't get in the first time HAVE gotten in eventually.
I think persistance is the key, along with trying to identify where your application went wrong. Also, it could be that you simply applied to the wrong schools.
Above all, I would be in direct contact with the schools and find out why you weren't accepted, and discover what you can do to better your application.
Most schools will gladly tell you what you can do to improve. If you take that advice to the bank, I think you'll find yourself a successfull applicant.
