Yes, many of us become nervous and controlling emotions cannot be learned from the books. The books and literature only teaches you how to. The rest of the work is yours depending on the application of what you have learned but I think facing the occasions make you strong enough to control them. Simply is that practice makes a man perfect.
I agree , to deal with your emotions you need to experience and face it first and identify your weakness in particular events .
Teachers and in school emotions are not taught how to control it well so it will be base on our own experience .So to control it you need to think whst are possible thing to happen if you do it know a lost again ?
