That graphic is pure genius I LOL a lot with it but in a serious note we must understand even if you had all the technical skills in the world it does not mean you have the right character and personality to ride the ups and downs of the market, you need a very special personality to do so.
Aaaaand this is the most important reason that I'm for algorithmic trading: I do NOT have that kind of personality, but I can sure formalize a strategy and leave up the stressful task of executing it to a machine.
