Nobody remembers the other people that tried building a flying machine before the wright brothers. Nor does anyone remember how many times the wright tried.
All we remember is their achievements. Their remarkable success that became a defining moment in astronomy and aviation. Such is the sweet taste of success.
A friend of mine will always say "Success has many friends, but failure is a bastard". The joy of being successful are not always the same.
Imagine the joy of a lil boy who after toiling for days finally solves a very difficult maths problem. His joy can never be compared to the joy of a boy who had to cheat to pass an exam.
In as much as we all wanna be successful, we ought to achieve success the right way. So that our joy will be pure and complete.
