"Generally speaking, the significance of the indirect results may very often be of more importance than the significance of direct ones." Making linear income (direct path) will never make you rich. Doctors make linear income. Engineers make linear income. Lawyers make linear income. Teachers make linear income. Trading is not just about compounding money to get rich. It's all about treading on the non-linear (indirect) path!
I agree. Unfortunately 99.9% of all banks, trading firms and individual investors live off the nipple of what linear returns provide.
