Dear experts,

I am in my mid-40s and now in a mid-life crisis.
I work as a manager in the back office of a financial institution.
I work well with others but due to nasty politics, I'm unable to climb higher.

I feel very down, everyday going to the office, knowing that I am not realizing my full potential. I feel like quitting, but with family obligations (mortgage, kids, parents, etc), I can't do that.

Changing to a new company is also not easy in this environment. I'm thinking of joining the teaching profession or perhaps become a real estate agent or financial planner.

Can any experts here help advise? Currently I'm earning $110k per annum. Would these jobs give me that much?

What would you do if you're in my situation?
