Discipline allows you to trade effectively. You can take your ego out of it. You can go wrong 60, 70% of the time and still make a lot of money. If you ignore the discipline of managing risk, you have to be right 80% of the time or more, and I don't know anyone who's that good.
If you're very liberal, then you should go and find a very liberal Zen teacher, a liberal interpretation of the doctrines of the Soto or Rinzai schools.
