Discovering one's potential is one thing and maintaining such potential to remain at the top is another thing.
Staying at the top of your potential can even be more difficult than reaching it. It is very competitive at the top for who will remain relevant there. It is not enough to reach your potential, you have to not settle when you reach it so that you do not begin to fall slowly even before you can realize it. To remain at the top, you need to be committed to development and growing in knowledge and skill. If you settle with the knowledge and skill that you have, it will not take long for you to become less relevant.
