Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.
– Steve Jobs
The one universal truth is that we all must die. Hopefully that day is far off in the future, but it is inevitable. As you age you will begin to realize how short life really is, and how fragile it can be. Consider your mortality every once in a while, it will make the present that much sweeter.
