An option could be focussing on and handling something which you do have total control over, exploiting the instances you're right to the maximum, compounding profit and reducing risk in a commerce, having reduced overhead, and less probability/need of overtrading.
The option of whether to exploit 1 trade for all it's worth, without risk, rather than taking the cash and running over and above, with much more risk, really is a simple and logical choice to make for me personally. I can't understand why anyone would purposely avoid the chance to make money...
