What doesn't kill you, makes you stronger. آنچه تو را نکشد، قو | English with Noushin نوشین لقمانی

What doesn't kill you, makes you stronger.
آنچه تو را نکشد، قویترت میکند.


It means that you will run into many obstacles in life. If you overcome them, then basically, you become stronger.
So, if the obstacles "kill you", you've made no growth or progress. But if it doesn't kill you, you've grown stronger.

For instance:

Your boyfriend left you for another girl. You learn to use better judgment in the future. You've become stronger.

Your co-workers gossip about you behind your back. You learn to confront them and express your displeasure in their immature behavior. You've learned to use your voice. You've become stronger.

There is a death in the family. A loved one is now deceased and they played a major role in your life. You learn to move on and cherish your time on Earth. You've grown stronger.
