the best thing you can do
is to be exceptionally good at something
you're the best
if you're the best doctor in town of your the best lawyer and down whatever abilities you have can't be taken away from you they can't actually be inflated away from you
somebody else will give you some of the wheat they produce
cotton or whatever it may be
and they will trade you for the skill you have
so the best investment
by far as anything
that develops yourself
