When you believe in your method you don't need to be discipline. The discipline is build in when you believe. Discipline is hard to maintain. Believes are integrated in your personality.
What has helped me is to think about it more as "it's irresponsible not to do _____"
If you look closely at the roulette table there is a betting limit with a maximum bet. It stops a big bankroll from using a martingale system. Basically limiting the houses losses. It's the same as discipline with a trader. Limit your losses.If you have a profit factor of 80% and make a hundred trades , then tell me it's all about discipline , and again have a break even strategy that loses with costs , make a hundred trades and then tell me it's all about discipline . You can play roulette with all the discipline in the world , you will lose , conversely the house has no control over it's "trading"( the bets and behaviour of it's punters) and yet given enough "trades " always wins .
A martingale system on roulette is still a losing system in terms of probability. "So many traders" blow up because they don't have winning systems , probability is against them , though they may be stupid enough to believe it is a winning system and that they lose because of of some personality trait , it couldn't possibly be that their trading system doesn't work.If you look closely at the roulette table there is a betting limit with a maximum bet.

The house can't go on tilt, a trader without discipline can. Why do you think so many traders blow up?
If you have unlimited funds a martingale system will eventually win back your original bet. That's why the house has a betting limit.A martingale system on roulette is still a losing system in terms of probability.

And you really believe this ? simple math will tell you the exact opposite , this is basic , not just a dumb statement , but a very dumb one ,infinite bets with a martingale system and a house take , leads to infinite losses .If you have unlimited funds a martingale system will eventually win back your original bet.

Unless you have the discipline to follow your system you'll never be sure if the problem is the system or the trader.
