I wish I took some time off in between startups. I’d suggest taking some time off to clear your mind and rejuvenate. If you have the ability, traveling can help (although this is tough now with the virus outbreak).
Definitely this. I have lived through two (one major) restarts.
Be gentle to yourself. You probably will need longer to recovery emotionally than financially.
Let the process take its time. If you're unsteady emotionally or under pressure (need to make a business to regain income) it is very difficult to make pragmatic decisions.
Agreed. Many years ago I left a job that had ground me down and started the next thing immediately, which went better. But 3-4 years into it, I realized I hadn't had a proper rest in several years.
Whatever your next thing is, you should start it with fresh energy.
