I read in some book something that I really liked. It went something like this-

"The Wiseman said:

I have to tell you something, something that's going to be hard for you to understand and accept. I wanted to painted in colors and decorate it with flowers of sweet smell and promises of love, but that would make to sense to you right now. You are going to die. I don't know when, it could be today, tomorrow or in 50 years, but you will die. There's no margin of error. It is certain, and there is nothing you can do about it. It will happen, whether you accept it or not. So...think wisely about what you're going to do today, and tomorrow, and the rest of your days..."

I'm 22 years and 234 days old today.
