Strength is an outward showing. If you think that anyone just feels like they can take on the world all of the time, you're wrong. Everyone is scared. Some people just push through it, in the hopes that it will inspire others to push forth as well, in the hopes that it will get better; it will get better. Create an epidemic of inner heroism, of inner strength. Sometimes you just have to do it. You just have to keep going, even when everything inside of you is screaming for you to stop. When others start believing you are strong, you will too.
