Some people work around this by front-loading some hobbyism in their day, starting in the morning and getting up early.

I've reached a point now I feel drained after a work day, whether I concentrated a lot or found it boring. And controlling for sleep. For this reason, if something I'm interested requires more overhead, I try to do some early or at least plan and set it up, so that once work is done I can just go through the motions without thinking about it too much.
