For me trading can be briefed into 3 steps:

1.Patience
2.Controlling greed
3.Controlling fear.

If you can follow all 3 mentioned above, you can be a successful trader.

Patience -- Wait for the right oppertunity to take a trade.
Controlling greed -- Fix up a target and close your trade whenever it hits TP or close a part position and let the other run with BE SL.
Controlling fear -- Do not get panic if trade goes against you, if it is going against you cut your loses short and wait for the next trade, keep a SL at as per your risk but do not wait to get it hit.
