Success is almost totally dependent upon drive and persistence. The extra energy required to make another effort or try another approach is the secret of winning.
When you make a mistake or get ridiculed or rejected, look at mistakes as learning experiences, and ridicule as ignorance. Look at rejection as part of one performance, not as a turn down of the performer.
Success is not a pie with a limited number of pieces. The success of others has very little bearing on your success. You and everyone you know can become successful without anyone suffering setbacks, harm, or downturns.
