“That which does not kill us makes us stronger.” Friedrich Nietzsche
This is true for overcoming physical challenges, but also for overcoming mental challenges.
The biggest mental challenge sometimes isn’t even real. It’s the fear of “what might happen” if you do something. A lot of times, it’s that fear that holds us back from achieving our full potential. We fear that we’ll fail, that others will judge us, that we will be rejected or look dumb. Those fears might be realized. Nobody is immune from failing. BUT, what we need to focus on is not the failure itself, but rather that we mustered the courage to take action.
It’s just like Teddy Roosevelt’s “Man in the arena” speech. In it, TR says:
“It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.”
When you face your fear, you feel like it’s going to kill you at first, but it doesn’t and you are stronger for it.
