How should my investment porfolio look like at age 24?

Unless you plan to head to grad school full time and might need funds for that, you might have a couple asset allocations.  The first obvious one is the long-term savings like a 401(k) or Roth IRA - unless you're just naturally very conservative, go for growth there.  Granted the markets in the short run can corect and lost value, but you're betting for the long haul and 90-100% equities will at least give you a shot at the upper-single digit returns you need to retire early.  If you're saving for a house or grad school, go ahead & save but don't go all growth in there - a much more conservative allocation, even up to 100% cash, might be right for those goals.  The earlier you get started making those deductions from your pay into a Growth portfolio, the faster you'l retire...it's really that simple.
