It might be an XKCD comic. It’s a graph that shows power vs. responsibility, or something like that. It shows that when you’re a kid and have little power and little responsibility, life is OK. As you go to college and have more power, but not much more responsibility, life is better. Right after school, you have lots of responsibility and little power, and there’s a big drop. Then, in retirement, it gets better again.
Any ideas?
