Remember you will die.
“The Latin memento mori is often translated as ‘Remember you will die.’ … For me, it’s a call to action and a benevolent warning not to squander time.”
— Tim Ferriss, in The Four Hour Chef (p.564)
Time is precious and limited. Do not waste it. What do you want to do with your life? How do you want to spend your days? Get up. Get motivated. Remember, you WILL die. Until then, I suggest you LIVE.
