In the moment I reached that conclusion, I was able to take actions and make decisions that just were not possible previously. Without certainty you cannot have committment. Without committment you will not produce the behaviours required to make it at this game.
Quote from mathewt:
I have personally met dozens of very long term profitable traders.
However a good majority of them had some type of edge:
Pit traders, market makers, arbitrage specialists, high end black boxes, etc. - all long term successful traders.
There is money to be made - you just need to find your own edge.
