I love this metaphor for how to live a meaningful life, “Live a lifetime in a day,” shared by Harvard physician Dr Aditi Nerurkar on The Diary of a CEO podcast. I took the liberty of emphasizing each of the 5 stages for easy reference:

“[w]hat creates a meaningful life… is to live a lifetime in a day.

And so that sounds like this big thing, but all it is, is that when you start your day, think about five things,

five things that you can do in your day to create an arc of a long and meaningful life in one day.

So what does that mean?

Spend a little bit of time in childhood.

So in wonder and play, even if it’s for a few minutes, do something that brings you joy for joy’s sake.

Spend a little bit of time in work.

We all know what that is, and for most of us, it’s a lot of time, but for, you know, it doesn’t have to be paid work, but just something that helps you feel a sense of productivity agency that I can do difficult things and I can overcome.

Spend a few minutes in solitude,

very important for all of the reasons that we’ve talked about today.

Spend some time in community,

so engaging with others, and then

spend some time in retirement or in reflection,

really taking stock of your day. So at the end of the day, when you’re going to bed and you’re putting your head on your pillow, you can say, okay, yes, I lived a meaningful life. I did all of those things.”

What a beautiful frame to start your day with. Usually I’ve got more reflection to contribute after I share something like this, but I really don’t this morning.

We’d all be a bit more happy, more appreciative of the life we live, if this was our daily goal.
