Discipline, commitment and persistency make the difference.
Consistency is the only path to success to slowly build an attitude of discipline and to give you the opportunity to accumulate profit.
This will reinforce your mindset of winning which will help you to form habits that will lead to consistency.
The trader has to accept that he cannot control outcome.
Instead of certainty of prediction, trading requires the management of probabilities where outcome is never certain.
And remember........ you must know the point at which you are wrong, and get out.
