Controlling greed and emotion is something that cant really be done easily unless if you do have already the experience on this market
Experienced or don't have experience has not guaranteed that you will always win against the market, even experts may experience losses too. That's right, it's not easy to control our greed and emotion because we are human and most traders will face that the same problem. Accept losses and learn these experiences and don't let them happen again in the future.
There's no straight winning result in trading and bear in mind that the market price is unpredictable and now one can predict it.
Losing is something that cant be avoided but somewhat can be lessen if you do already have the knowledge and experience.
I tend to agree, it's well said.
