Just get a comfortable asset allocation. As others have mentioned here, you're young enough to not even give bonds a passing glance. With a 12+ year horizon, diversified stock portfolios will far outstrip bonds.
90/10 seems smart to me. 80/20 if you're really worried about a correction.
FWIW, I'm in my late 30s and my portfolio is roughly 95:5 stocks:bonds (or bond equivalents).
