How to develop confidence in oneself?

Q: I have been a very poor student since childhood and I don't know how to manage my life. I want to change this world but I am not intelligent and hard working. I want to discover new scientific machines and also new economic policies. But I am currently in commerce background. I want to become a genius like Albert Einstein and Thomas Edison.

A:From you question it is not clear what the real concerns are. However, it might be useful for you think through what difficulties you have experienced until now and assess your strengths and limitations. Then set some reasonable goals and strive for those. Do not start with a very large goal it will be harder to achieve and in turn the risk of being disappointed is high.
