Mastering emotions is important. Especially when it is very likely that all our actions are triggered by emotions, even if there is some logical justification behind.

Emotions should not run our decisions (especially in investments), but we should be aware that they trigger our actions. An analysis doesn't make you buy or sell, an emotion likely does. You may feel cautious, fearful, or greedy, for example. That's why you push the button. The feeling may come without a clear reason (a sentiment or you got influenced), or it may have a logical argument behind.

We may be able to train ourselves not to react to first impulses, but eventually we likely need an emotion to make us push the button.
