Quitting because you don't want to be uncomfortable will prevent you from growing.

Truly successful people don't rise to the top by acting tough; they become better by growing stronger.

Building mental strength is about learning to regulate your thoughts, manage your emotions, and behave productively despite whatever circumstances you find yourself in.

It'd be nice to learn enough from each mistake that we'd be guaranteed to never repeat that same mistake twice. But, how many times have you said, 'I'll never do that again,' only to find yourself right back at it a few days later. Learning from our mistakes requires humility and a willingness to look for new strategies to become better.
