A little over a decade ago I founded a community driven website, after some growth I started work on the site full time but discovered I wasn't the right person to lead a business, induced by stress I sold the website on condition I would remain in position. True to their word I remain in position to this day, yet in the years since I've found that business interests and community interests diverge and the community I am passionate about has suffered for profit. I'm burned out, the community is my life, everything is connected, skills, contacts, how do I move on? Matt found his future in writing, where do I find my future?
Quit and do things you like instead. You can always build new contacts, skills, and connections. Once you burn out you are just dragging along, it's painful and it's pointless.
I've been in three completely different fields for 3, 6, and 10 years respectively. Once you find something you like, it's very easy to dig in and build a new network and learn. Don't be afraid, be excited. The worst is when you are doing something you feel dread for or don't want to get out of bed in the morning for. Happy to talk/answer any questions.
