Not quite ....
A Good investor knows that A Good Investment is one that can continously compound return for you, but carry the risk of losing big time overnight, if not everything.
So if you are a Good and Rational investor, you WILL set aside some of the current return and practise like a Young Work Force.
That way, no matter what happens to your current investment, be it losing everything. Its ok, because you have the capital to restart the legend again.
