What was the big move? Little did I know it back then, but the solution has many parallels with non-convex optimization: I got the heck out of the local minimum I was stuck in life - moved continents, changed careers, changed the people in my life, changed the culture around me.
Concretely, I went to grad school abroad and settled there. It took adjusting and lots of work, but I now make multiples of my previous salary, dated beautiful women I never would have in my local culture and had a choice of awesome people to become my close friends.
You might be stuck in a local minimum too - starting anew can be good for you if you manage to do it. Maybe you won't even need to go to a new continent, but the lesson is, make big changes!
