The purpose of investing is to put dollars into something and get more dollars than you put into the investment back to you.
All of those dollars could be considered like little soldiers, and they all have a specific job to do, which is to go out and capture and return with additional dollars, which then are new and additional dollar soldiers for you.
The idea is to put EVERY soldier to work, and arrange things so that each soldier gets maximum production.
The catch is that the soldiers are only as good as their leaders. The leaders have to make the investing decisions and deployments, so to speak.
The trick is to increase your investment IQ enough so that your soldiers are constantly winning the battles.
