I regard the amount of brainpower going into money management as a national scandal. When some idiot would get rich, they'd say, 'Well, old Charlie was out in the field playing the big brass tuba on the day it rained gold.' A lot of people have become rich lately who were playing the tuba on the day it rained gold.
