Self-belief basically means trusting oneself. It is important to have faith in yourself and the task you are doing, only then you can rise up to be successful and happy. Self-belief is the biggest key to success. Once you believe yourself, you can let go off the fear of failure. If you lack the faith and belief, you will lack in action, and thus, you won't be having enough guts to stand up for yourself. People who do not believe themselves will eventually lack the confidence for doing something, and thus, they tend to set their bar too low. People who lack belief upon themselves will eventually have low self-worth and thus, become underconfident. Hence, they won't be able to run at their full potential and move ahead. There is nothing called 'impossible'. All you need is to believe yourself, and you are sure to achieve everything that you are thinking of! Self-acceptance is extremely crucial. Once you are able to see your worth, you will be able to have faith in yourself. A person who accepts the fact that he is walking along the right path will eventually find a way to make it up to the destination. On the contrary, if you have uncertainty about yourself, you will remain in a dilemma whether or not you are moving along the correct path.
