Quote from kiwi_trader:
Actually it says "Those who speak do not know."
Which is clearly an ancient and enlightened way of saying "if they offer a verbal/written solution they are full of shit."
I don't see any mention of homework in it. bs.
And back on topic, I learnt by reading a lot of books, many useless, asking people about things, sharing ideas with others and making 1000s of mistakes (in every sense of 1000s). If it boils down to anything it is: There are lots of good ideas out there and you have to distill out a few that feel right to you. Then you have to try them in as real a cashless situation as you can to prove that they work at the hard right edge. Then you have to apply money to them. And when you overcome your psychological issues and the slippage, mistakes, and operational issues that come your way you can be successful.
I think that if I had found the right mentor early on (= honest, insightful, method compatible with me, and can help me see where I am going wrong) I could have reached journeyman level in this art much less expensively.
