“You cannot be anything you want to be—but you can be a lot more of who you already are.”
So much of our lives can be spent in the pursuit of something you think you want, yet isn’t coming from a place where you are maximizing your God-given gifts. No matter how much I like running, I am never going to win marathons or half marathons. This is just not what my body is built to achieve. However, I can still enjoy running and I can still enjoy the distance and I can still improve on what and who I am within the sport.
The key to success in life is to develop extreme awareness of self, who you are and what powers and drives you. Then put your full and complete effort into becoming more of that person, better at those particular things.
Developing this sense of self means you must become finely attuned to what and who you are not so that you can dedicate the time and energy into being the best version of the person you built to become.
Know your race. Run your race. Improve on your race. That is how you win.
