Park your ego at the door. (the larger the ego, the lesser the knowledge) Stay disciplined. (treat it like a business which it's fun and challenging, not the other way.) The best strategy and plan is the one that makes you profitable. (if you can't explain it simply, you can't implement or execute it successfully.) Market is like a woman, don't try to understand it, just treat it with the utmost respect and remember that they are both always right. (sorry for the lack of gender neutrality on this one, was passed on to me from an older generation)
Lot of mention has been made about studying charts religously. Yes, this needs to be done during the learning curve times to understand the behaviour of price action, but there comes a time, studying charts becomes too time consuming. One cannot everyday be studying scores or hundreds of charts in order to make a decision. One will also fall into the trap of analysis paralysis. Study charts to learn, but don't study charts to trade (so much). One needs to revert to maths based, it is far easier and offers quicker wider ranging information than by studying individual charts.
