Imagine three people, A, B, and C, sitting in different rooms of an experimenter’s lab. Person A has a choice: to accept 10 units of fun (consumed on the spot, e.g. playing the first level of Halo 4), or to accept 1 unit of fun (also consumed on the spot, e.g. listening to the first song on Halo 4′s soundtrack) plus a wooden token. Person A then leaves the lab forever; if they received a wooden token, on their way out they toss it to B.
Next, Person B acts. If they received a wooden token, they can’t do anything with it. They’re faced with the same choice: 10 units of fun, or 1 unit of fun plus a wooden token. Then they leave the lab forever, and toss their wooden tokens (zero, one, or two) to Person C.
Finally, Person C acts. If C has zero wooden tokens, they’re given 10 units of fun. If C has one wooden token, they’re given 100 units of fun (e.g. playing Mass Effect 4 in its entirety). And if C has two wooden tokens, they’re given 1000 units of fun (e.g. an advance screening of the movie Deus Ex: A Deepness In The Methods Of Rationality). C then leaves the lab forever, possibly on a stretcher due to awesome overload.
What do you think will happen here? A and B might grab their 10 fun units each, leaving C with only 10 fun units. (This would be much more likely to happen if A and B weren’t told the meaning of the wooden tokens. It would be virtually guaranteed to happen if the wooden tokens were abstracted away entirely, leaving the experimenter to “compute” behind the scenes what C gets.) A and/or B might also decide, altruistically, to give up 9 units of fun so C gets 90 or 900 more.
Now run the experiment with Person D, except that D just walks out of the first room, puts on a hat labeled “Person E”, runs the second step, walks out of the second room, puts on a hat labeled “Person F”, and runs the final step.
Now replace the rooms and hats with a simple timer, counting chunks of minutes/days/years/etc. Adjust the reward numbers (1/10/100/1000 fun units) as you see fit.
The point of this thought experiment, phrased in a silly manner, is that at any point in time, you can imagine yourself as being either A, B, or C in the temporal version of the experiment. Suppose you’re person B (Current-You). Person A (Past-You) is all-powerful, having already acted and left the scene forever, taking their fun rewards and leaving Current-You wooden tokens (or not!). Current-You has some level of power: you can choose your own level of fun rewards, and whether to accumulate more wooden tokens to give to person C. That’s Future-You, who is completely at the mercy of Past-You and Current-You combined—but you’ll become Future-You so you probably want to keep their interests in mind.
Who do you think you’re stealing from?

This is actually how I view my own life.
Sounds fun...
