Sorry to hear you're burned out. I can understand it.
For me, if I play more than 2 or 3 shows in a week, I start thinking it might be nice to have a day off. Between the day job and the music thing, I'm pretty busy during the summer.
But the part that feels like work is the 30 minutes before and after when I'm loading my stuff in and out and setting stuff up. As soon as I start playing, all the feelings of work go away.
If I could play only at venues that have their own sound systems so I just have to plug in, I'd play 7 shows a week
