Why would you do it? Why not find new job before quitting? I understand that some people can thrive when poor but it clearly does not work (based on this comment) for you.
I managed to find an okayish job in week, but I consider that an extreme luck. Fear of poverty is a mindset, for some it's stronger, for others it's less troublesome, to me it's strongly connected to childhood memories and not trusting my abilities.
