Always easier said than done my friend. Just look at all the technical analysis every day in forum and on Twitter. It takes hard work and a lot of learning and still, if the trades go against you, you lose money.
Patience is one thing but with real money at stake it can be hard to keep a level head.
Discipline. Trade in a group and have everyone pressure you into following stop loss.
