It depends how good are you at planning your time/money and what your goals in life are. People in tech tend to make ~2x the median wage, so if you set a goal of scaling down your lifestyle to save enough cash for a personal safety net, it's totally doable. It also doesn't have to be that - you can do consulting in parallel, or find a part-time remote job or whatever.

It's just a totally orthogonal skill set to fundraising. If you're charismatic and can sound confident talking about trendy topics, sooner or later you'll find someone willing to write you a check even if you are crap at planning and delivering.
