You can't be paralyzed by fear of failure or you will never push yourself.

Everyone has a mind, which continuously makes us think, creating fear of nothing. Our mind makes us think and think and think and by the end we think every possible difficulty and fear which will come in our way. Even though the path is really easy, our mind will make it difficult for us even before we have started. Example, you have to present a book and you have prepared really well and are ready with the presentation. But, then you start thinking while you are waiting for your chance and all nasty thoughts like 'what if I say something wrong, what if my presentation has a error, what if everyone laughs at me, etc.' strike your mind and your nervous organ starts working and makes you nervous and eventually make you do errors in your presentation. So, never ever let your mind control you. If you let your mind control you, you can never get anywhere or be anyone.
