They are all by-products of success rather than success itself, indicators that you perhaps succeeded in the more important contest. That real contest, of course, is striving to reach your personal best, and that is totally under your control. When you achieve that, you have achieved success. You are a winner and only you fully know if you won. Some of us are shorter or taller, quicker or slower, smarter or otherwise.
Some people have more opportunities, some less.
We are not the same in all these things, but we are all the same in having the opportunity to make the most of what we have, whatever our situation. The ultimate challenge for you is to make the attempt to improve fully and be your best in the existing conditions. I wanted to get this idea across to the youngsters I was teaching. I wanted them to know that making the very most of what you have is success and that it is something you control. I wanted the athletes I was coaching to understand this as well.
