"If it doesn't kill you, it'll only make you stronger."
This quote is simple and straight to the point. It gives me alot of motivation whenever I feel like I just can't do it anymore! I use it on every single difficult aspect of my life.
Like when I'm running and I feel like I'm dying and I'm ready to give up anytime, I tell myself it's painful but since I'm not dead yet it probably is making me stronger.
And the feeling of victory afterwords is just sweeeet! ^^
