You’ve been given a hand to play with. There is no point in dwelling on your inherent nature or your perceived shortcomings.
If you’re less patient than others, you can get things done quicker.
If you’re short-tempered, you can harness your discontent to propel you forward.
If you’re opinionated, you can make yourself be heard easier.
Just make sure you’re self-aware enough to use your inherent nature to your benefit rather than to your detriment.
