A child was sleeping in a classroom. The teacher wrote a question on the board and said that, "this is the most difficult question in the world & no one can solve it". When the Teacher finishes the lecture, the Child will get up & the teacher repeat his question & tell to the whole class that try it at home. The next morning, teacher start checking, No one child can solve that Question in the class but that sleeping child had solved it Because his ears never heared that you can't solved it. Your doubts will kill you it overwhelms your Mind & for God's sake, avoid those who created self doubts for you.
