No wise man ever wished to be younger.

Whatever is lost with age, the thing gained is understanding, and nobody who has it would trade back. Youth looks enviable from a distance because the losses are visible and the confusion is not, and a return would mean going back into every uncertainty you have already worked through. What you would get is energy, and what you would give up is knowing what to do with it. The exchange is worse than it looks.

Rather than measuring yourself against a younger version, name three things you understand now that you did not then. Spend the week using one of them on something that would once have defeated you.
