With the help of nature anyone can manage their emotion easily.
Managing emotions comes with strong self-discipline. It may not be easy but for people who badly needs it, they will find a way to be able to do so. Controlling emotions while doing trading is very hard especially if the market price keeps on fluctuating up and down. I have experienced it while I was exchanging one of my token. I was frustrated because the market price of that token goes down just at the time when I was exchanging it, I needed the money at that time.
I control my emotions by listening to music. It is proven that by doing that, music changes your mood. I like listening to POP music and R&Bs.
