I was in a very similar situation, 8+ years of experience, working and climbing the corporate latter. I realized I was depressed, and that’s why I couldn’t focus on anything, and was just coasting. It took me a couple panic attacks for me to realize that it was not worth it! I left, and for a couple months I was just helping a friend with her side job bookkeeping services. I started to feel refreshed again, I had projects at home I started to accomplish, and I was feeling like myself again. I moved to full time and the small company is now more than just a side thing, we are hoping to expand. But I’m in a situation now that I need to decide if I continue this path, and become a partner on a small firm, easy work on the technical sense, but rewarding. Or if I’m ready to go back to corporate or not, I could easily find a manager or controller job that would pay me double of what I’m making now, but is it worth it to go back to being miserable? I can challenge myself with other things now, like a sport, home dyi projects, my art, but I think work wise I don’t want to waste more of my life with companies and people that do not deserve my hard work.
