Why do you need a why? Because some days you're going to say I don't want to get up, but that's when you're going to say I'll push yourself to get up.
Yes, you're correct. The reason why I need "why's" is because when I get to the point where I stumble and find it difficult to get up, I will answer it, "It is necessary, because I am also needed by myself and the people who surround me." And because I still need to prove to myself that even though I already reached my limitation, I will continue to fight the challenges of life.
