Be confident. Too many days are wasted comparing ourselves to others and wishing to be something we aren't. Everybody has their own strengths and weaknesses, and it is only when you accept eveyrthing you are - and aren't - that you will truly succeed.
It takes a while to understand what is true successes vs imagined dreams of success. That is why many fall after attaining what they wanted. Think of lottery winners. Condition yourself as you go to the top of your abilities.
The real secret of success is enthusiasm, having a great attitude towards everything will make things better for you and other people. By being enthusiastic you bring a positive attitude and make others day better.
