Yeah, patience helps you to think holistically by keeping in mind the amount frisk you can take. If you don’t have patience you will focus only on your loss part and can never have strategy to get yourself a safe escape.
To improve patience we need to be realistic. When it comes to forex trading, people become illogical. They want multiply 100$ in a day. Market moves all the time doesn't means all the pips are yours. Be realistic and treat it like a normal business.
