I feel you. I've spent more money on synths than would be healthy. I've bought and sold the same synth multiple times. The new and shiny thing is always so attractive...

I've yet to find a solution. What helped me temporarily is forcing myself to make music. I am ha hobbyist, not a professional. So I don't put a value on my time making music. Me making music IS the value.

So what I did for a while (until I got too busy to pick them up) was make music for people who needed it and release that music into the public domain. Kinda like open source music. I got a few people who were making documentaries, videogames, video stories, and the like. It was good to have someone you'd disappoint if you didn't make them a full track. I drove me to actually get the music done.

But when I got too busy, I shut down the website.
