Age counts the laps. Growth counts how you ran them.

Time passes at the same rate for everyone, which makes age a poor measure of anything except how long you have been here. What varies is what happened inside those years, and two people the same age can be carrying wildly different amounts of learning depending on how they spent them.

Instead of measuring yourself against other people’s ages and milestones, look at the last twelve months and ask what changed in you. If the honest answer is very little, that is worth acting on. If it is a lot, the number matters even less than usual.
