Memento Mori
I'm a stoic. At least I think I am. I want to be one.
I follow one of America's most productive and clear Stoics, his name is Ryan Holiday.
Today, in the mailing list I subscribe to, I found this (again):
“When you realize that as you are killing time, time is killing you—it changes your relationship with your life itself. That’s what Memento Mori is supposed to do. It’s not supposed to be morbid or depressing or paralyzing. It’s supposed to be the exact opposite: it’s supposed to be clarifying, it’s supposed to give you priority, it’s supposed to give you perspective, it’s supposed to help you realize how important the second in front of you right now is.”

If you want to learn more, watch this video:
And memento mori. Remember that you are mortal. That time is passing by faster and faster, so don't put off until tomorrow what you can do today. Because maybe, tomorrow never comes.
And if it does come: do more of what you want to do.
