What's that one thing?

[i_feel_slippery]

There's always one thing to remember in life. One important crucial thing. This thing came up today talking to Alicia. She insisted on an explanation and I insisted that I did not have the time or capability to draw the diagram. So I spent minutes upon seconds to create this diagram that I hope best explains what the one thing is. If you dont get the graph, dont ask me to explain it to you because this is absolutely the best way I have come up with showing it. So just keep this one thing in mind your whole life and you'll live a long one and never die*
