Those can play an ugly trick on you
Say, you persevere in and are determined for something which you are not naturally gifted with (like being short and trying to become a world-class basketball player). Then you will only be wasting your time and effort. Put differently, blind perseverance and determination can easily turn into an exercise in stupidity and futility. You should always practice "situational awareness", so to speak, i.e. how well something fits you and how well you fit in
You made Basketball as example but why there are very few players like Micheal Jordan and Kobe Bryant? because they are gifted and thats it.
