What makes you stronger

What making you stronger is not thinking about strength or reading about how to acquire strength, it's getting up, working hard, doing what you don't feel like doing and moving out from your comfort zone into the non comfortable fields. It's not going to sleep because you must sleep, but sleeping when you are over exhausted and need to take a break. What makes you stronger is overcoming one obstacle after another when you thought you don't have the ability to face any of them. Doing this will give you the power to build the strength you may even not realize that you have.
