What I don't know

If, for each new thing I learn about retirement/financial_economics/quantitative_finance, my awareness of the things I don't know grows with some type of exponent attached to it and if by definition the things I do add to what I know is some imperfect and linear process, then in relative terms I am getting dumber every day and I'm guessing that my knowledge, in relative terms, is probably asymptotically approaching zero.  Encouraging thought, eh?
