Your goal should be what you were designed to be. Nothing more, nothing less. Perhaps you are not a sprinter but could run the additional 60 yards in another 6 seconds? Perhaps even, you'll invent a cure for a form of cancer 20 years from now.
You have an, as yet, undiscovered talent. Keep your mind open and it will
: When I was a mere child of 16, I could do 40 in about 8 seconds, 100 in 14 but a mile in 5:14. Today I do the 40 yard dash just slightly faster than a toad looking for bugs.
The day you stop learning is the day you should die.
