Jerry Seinfeld has a hilarious 1 min 20 sec bit on his three selves – night guy, morning guy, and day guy (YouTube link).
In the bit, he explains that the night guy doesn’t really care about the morning guy when he’s up late. The morning guy, on the other hand, can’t do much to get back at the night guy. The only thing he could do is sleep in late so day guy might lose his job and thus prevent night guy from having enough money to go out.
In sharing this bit, he beautifully captures the challenge of making investments in our future self.
And, yet, the more empathy we can create for our future self in our here and now, the better our decisions will be.
