Oh, if we were all perfect, we would be rich without exception! Of course, each person has different qualities, someone less greedy and more patient, another greedy and reckless, you need to learn how to find a balance and be more resistant to market situations!
We are not all perfect but as a trader we have to strive to learn.
Greed is already within us but we need to control that and make a decision that has a solid basis.
Being a trader we always make judgement based on proper research and not purely based on what and how we feel, as it's not surely gonna work.
