How to stop prototyping concepts

You’re lucky. I haven’t been able to come up with a concept in ages, let alone a fun concept.

Lol, I haven’t had this problem since the beginning of my biggest project in October 2006.

Is that not still kind of like a prototype?

I have concepts all the live long day, but lose all motivation to write them as soon as I sit down. I think it’s because programming is also my job. I’m wearing out one part of my brain and not exercising the rest.
