Why to temper steel?

Difficulties. Pain. Struggle. It's all good for you, just need to handle it correctly. It's like stretching for the splits. It hurts like hell when someone pushes at you, but next time you do it, pain gets duller and you can move further. You learn. Some troubles can be called mistakes, with others - that's just part of life and you should accept it. Just another experience. It'll help you in the future.

You will never become that "you" until you get out of your comfort zone over and over and over again. Embracing those stupid challenges, trying things, not being afraid. Ha, nice words, but doing it is so f-ing hard. It will feel good though...later.
Steel needs tempering. Without it, it will not be as durable.

To all the assholes not believing in me - I made it pretty darn far. To all the fools who thought that pretty words will do it - I never believed you to begin with. I overcame a whole load of roadblocks and I will only keep going. You'll see. I will push myself harder.

"Makes me that much stronger

Makes me work a little bit harder

Makes me that much wiser

So thanks for making me a fighter"
