Slowly, you come to understand what it means that profit and loss come from the same source.

A trading pattern that lets you make big profits can also lead to big losses;
A personality that lets you catch trends and eat well will also get you repeatedly stopped out during consolidations.

When you're in profit, you can't bear to take it, always wanting a little more;
When you're in loss, you can't bear to cut it, always hoping for a bounce to break even.
It’s the same human weakness that causes so many people to make small profits and suffer big losses.

Accept that profit and loss come from the same source, let go of wishful thinking, strictly stop losses, and take profits rationally—
Only then can you survive in the market for the long term.
