After 2 days of working with the history of all my Forex transactions made during 2004-2006 i stoped by this point:

80% of time the account balance was developing with such a trajectory (See image), the rest were strictly down:

All right till a time with trades: discipline, analyze, low risks, but, Every time i was approaching to a certain point, my mind tried and did everything to destroy all i started building. I mean my unconscious mind. Consciously i was "hardly" trying to turn back in favor of mine. In fact executing my deepest fears... That beastie, when feeling it can be defeated is fighting with doubled forces. Here, i guess, could be listed undisciplined trading, hi risks, nervousness, taking low motivated trades and much more...

My psychological status is not prepared to see a developing situation which can destroy status quo, all its views about "how to be"...

Of course, there are tons of information over the internet about discipline in trading, but most traders will fail.

Very actual quote from H. Ross Perot:

Something in human nature causes us to start slacking off at our moment of greatest accomplishment. As you become successful, you will need a great deal of self-discipline not to lose your sense of balance, humility and commitment.
