Everything that you enjoy doing is easy to do, time flies when you are having fun. If you only do what you already know how to do you will never challenge yourself to become more, to be better. If you settle you will become complacent and weak. Work and challenges are an essential part of life that you must complete. I know it is hard sometimes but you have the ability to push forward and amaze yourself because you are not aware of how much power you have until you push yourself.
Only through perseverance shall true strength be gained.
