Control, regret, courage and a lot more.
These are emotions that burst out whenever you decide to sell or buy.
If you can manage to get the best out of all that then maybe you can succeed.
It is true it cannot be learned in any tutorial out there.
What you need is experience by doing it over and over again.
It can really be attained when you do deal with a thing for how many times and you do keep doing it until you do able to grasp everything from technicals to emotional aspect.We can actually compare the emotions we felt when we are just starting up until we do gain experience.All is different and since we already know on how do things work then our emotions and decision making skills would really be enhanced and this thing wont stop until we are still engaging into any stuff. There are really things that cant really be taught by somebody since you are the only one whom would able to discover it along the way.Applying it on future things would really be helpful,
we shouldnt really stop trying until we do learn everything.
