What are some trading rules and tips you absolutely abide by?

Basically as the topic says, what are some absolutely important rules and tips you abide by while taking and trading decisions? How did you come to know or devise them?

The first thing I would like to say is that everyone trades differently, there are some key musts that pretty much everyone has to follow but the way you follow them is up to you.

Firstly, I will never ever exceed 2% of my account, you must come up with your own trading system and tailor it for you. Make yourself the most comfortable without getting overconfident.

If somebody tells you something that is too good to be true; it most likely is. Finding out techniques and tips for yourself is the best way to learn in my opinion.

Lastly, I am patient. If price isn’t right for entry there is still next time, don’t give into the fear of missing out.
