For the first time since I was in elementary school, I did a chin-up.
I’ve actually been working on pull-ups, which seems like a more useful capability: If you can do a pull-up, you have a shot at being able to pull yourself up onto a wall or up out of a hole. I’m not quite there yet. But along with my pull-up training I’ve taken an occasional stab at doing a chin-up, and today I managed it.
All it took was three years of ceaseless effort.
