Probability is not the key -- the odds are never fixed like a deck of 52 cards. You need capital to learn, to pay your tuition from the start, that is pretty much a given. But once you make it I think it's "psychological" capital that is more important than actual.
Those that play no limit poker can understand, you really have to not care about your chips at risk to be able to succeed. How do you get to that point? Confidence that you can always make those chips back. When it comes to the markets, I am always looking to learn more, to push harder to find new ways to apply greater amounts of capital over longer time frames (position size and trade duration go hand-in-hand, after a certain point). Why? Because even if I somehow blow it all, I know all I need is a few grand to get right back into it -- this gives me the courage to continually push myself. And you will eventually find yourself always pushing, if it's longevity you seek.
