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.
I do agree with your first point about patience but how do you recognize a good opportunity and the right time to trade? Greed in economic terminology is refers to the concept of monotonacity which means to prefer more and more though the concept of setting a particular target is nice and helps keep aside the profits that are earned as a result of growth in the values of the coin. And speaking further, a fearful man cannot pursue in the market no matter how desirable the situation are.
