By thinking, by imagining that we’ve just been given a few months to live, we can see immediately what we should stop doing. We realize we don’t have time to waste. And before you know it there is this urgent emergent need to do the things we love in place of the things we hate.
This is the positive side of the memento mori thought exercise: not “What would I stop doing?” but rather “What would I start doing?” How would I spend the limited time I had left? Where would I find meaning and purpose and joy?
The truth is that none of us know whether we will get to it later (of course, the tricky part is that we don’t know that we won’t either). So we must use this as a test. If you knew you were dying, what would you do more of? What would mortality prioritize for you?
Do more of it today. Because you are mortal. You are dying...fast or slow, nobody knows which.
