There’s a singular type of energy that comes from feeling that you’re good at something. That’s what they don’t tell you about getting older—it’s not the invisibility or the aches and pains that kill you. Instead, it’s that incrementally, and over a span of just a few years, you are perceived to be less and less useful to the world. And the belief that you’re slipping begins to calcify into the fear that, if you’re no longer good at something, then maybe you’re not good for anything.
