Quote from FaderTrader:
I think the moral of all of this is that if you want to trade for a living - making your own calls - you mostly need to buy your way in. Thank god for decimilization as it's lowered the barriers to entry (albeit the profitability as well).
If you accept that, then you'll agree that you need to live below your means in order to save the grubstake when you are young enough for the risk/reward to remain favorable (no kids, no mortgage, no real obligations).
If you believe that, then you'll agree that in order to actually trade successfully, you need to maintain a lifestyle that is below your means in order to up your size over time without risking everything.
If one is disciplined enough to forego the high-life for so long in order to learn to trade successfully, then they are likely the type who will do well in trading as they are probably doing it for the experience, not solely for the money.
I know I feel that way.
In the words of T. Boone Pickens: "I don't do it for the money, I just sure as hell don't wanna lose."
