Controlling our emotions is a little bit challenging if this is really what we are. It was easy to say "control your emotions" but if you are in an actual scenario and most especially if you are active in social media where FUDs and negatives are possible to read, you're going to gain some influence from that.
That is why if we can't change the way we usually reacted to a certain scenario, it is much better to keep a distance from trading as surely we can't do it.
I see holding is suitable for this kind of person, not trading.
