Opinion: Competing With One's Self
We are different people and our path to success is diverse. Even our successes are not the same. What makes another happy might make me extremely unhappy and vice-versa, so why chase the same things and why go about things as if life is some sort of race? Competing with yourself is learning to master yourself. To gain confidence in who you are and what you are about. You can be genuinely happy for others, because your friends successes are yours too. You don't crave what they have because you know what you have and you appreciate what you have, and you know you're using your abilities to the best of your capability.
