I was exactly this way ... maybe a year or so ago.

But honestly I've stopped being excited to type out code in my personal projects anymore either. I've become much more excited by what I can accomplish on my own in a small number of hours squeezed between work and family. I still experience this as a loss, but I'm no longer so sad about it, and moreso feel invigorated by the possibilities and opportunities that have been opened up.

A way that I have come to think about this is: I used to always be curious about the product management role. How exciting to come up with ideas and validate them with users. But I always demurred because it would be so frustrating to have to rely on other people to bring those ideas to fruition! On balance, I always preferred being the one executing ideas to being the one generating and validating them. But now I can properly do both things! (In my hobby time, that is, at work we still have this idea/execution split, at least for the time being.)
