I have a small account. I want a big account. .I am greedy, and I want to fund my account so I don't have to work anymore. It's a simple as that.
To make a living, I need 50k in operating capital. I want 3 times that in reserve. So I need to raise 150K.
Psychologically, having a stream of income to pay my bills really helps too, as that takes my mind off of them so I tend to not over trade as much. Ultimately, I win more that way, both in the number of trades, and I feel I can be exposed a bit more, so the amount I win each trade is also increased.
So it's a pretty selfish reason actually (although, I should probably not admit that publically).
