I would second the people saying to live cheaply for some time. In 4-5 years, you could become highly skilled in any one thing that you're passionate about. Often times you miss pursuing certain interests in your early years; simultaneously society forces you around in disagreeable ways. This is a chance to "correct everything wrong with your life," as much as that's feasible.
The obvious alternatives - blindly go work in some fashion, or spend your money funding a startup - are likely to leave you burnt out, because you don't have a good motivation yet. Once you've figured out your biggest passions, then work will be easy and you'll have no trouble feeling productive.
