Fear incapacitates people. Its hard to think and act objectively and wisely when you are in fear.
Here are my additions on how to deal with fear;
First fear is a fact you should know that, everybody fears something. But they still go after their dreams anyways, so why not you?
Second, most limitations and fears we have in our heads are not placed there by people but by our own imaginations. Why kids fear darkness, because of their imagination not because there's something in the darkness.
Third, do not compare your ability with other people, you will never be anybody else but you. To do not seek to impress anybody but express your talent, do not compete anybody but compliment others and compete with your own self.
Fourth, face your fears. Let fear fear your talent, ability, passion and determination. I remember back in 1991, my brother son used to fear so much, aircrafts when they pass in the sky and he happens to hear the sound of it, could run inside the house crying at the top of his lugs. But one day We took him to the near by airstrip, because we lived in the vicinity. When we reached their he saw a small plane, he asked uncle what is that we lied to him we told him it was a car. He relaxed. But time came for that plane to take off, all hell broke loose. He shouted, screamed and cried, but we held him tightly he could not run anywhere. Within few minutes his ordeal was over and thus his fear of planes henceforth.
So the best treatment for your fears is to face them head-on.
