While it is certainly true that successful people are endowed with ability, this by no means ensures success.
It is not the person with the best idea who is successful, but rather the person with a good idea who acts upon it.
Perseverance in honing and refining that ability along with a strong desire to make a difference are the keys to success.
Where do need and ability intersect? There lies opportunity. All that is missing is a persevering determination.
