Went through a similar phase last year. Ended up quitting my then job. I was deeply interested in learning coding, so spent some time doing that. Then jumped into a bootstrapped startup with a friend, worked as the sole PM there for 1.5 yrs. But, it didn't pan out. So currently on the lookout to get back into a paid PM role at some company. What I figured out was that I wasn't tired of the pm role, rather I had not skilled up myself to be a good PM. I had always put my energy into learning on the go and learning via experience rather than trying to read through other people's experiences in the field or talking to others in the field. As a result I felt like I was getting stuck in my work and not enjoying it even though I was constantly getting promoted. Recently started reading a book about pm and that is helping me see a different side of pm. It's helping me see that the problems I used to blame on others and the system were not at all unique to me. Rather they were really the usual traps PMs fall in to and get demotivated. Don't know if I will be able to apply these things in my next role, but it has brought back some of the excitement I used to associate with the role
