Go aggressive, this is what my portfolio looks like

58.42% DFA INTL VALUE II
18.98% LIFEPATH 2040 (Fidelity)
11.42% T ROWE MID CAP GRTH
10.01% VANG GRTH INDEX INST
0.60% FID GROWTH & INCOME
0.58% INDEXED STOCK FUND

97% of my portfolio is in stock investments (international has been good to me for the past couple of months) and I see an average return of about 12%-17% a year.. not too bad all things considering.

I did change my asset classes this year so the 12-17% based off of previous asset allocation and not my current one.. I'm trying something a bit different this year with 58% in International funds. I'm down 3.9% this year (an improvement from -11% in february) but the way the market has been the risk is more than worth the reward in the long run.
