If you followed your trading plan but still lost money... you still won.
You won a psychological battle, and this should be celebrated.
Over time, consistent actions beget consistent results.
A big issue for traders is that most of the time there's nothing to do.
And because of that, people will seek to do things to keep boredom at bay, which often means over-trading.
Before initiating your trade, you need to know what you stand to win and what you stand to lose.
If at any point this is unclear, then the trade isn't worth it.
