If your objective is to stretch the $20K out over a long while through reducing your living expenses, I don't doubt you could make it last if clever enough. However, if your objective is to turn that $20K into a much higher sum and gain much higher % returns (which I think Altucher was referring to), given the age range (20's), and the amount of capital, it makes sense to parlay that into knowledge and experience.
