I think it's best to listen to your inner voice and still make a sensible decision. Evaluate what would happen if the worst case happens, if you wouldn't make it, what would be your option? For me it was the right time. I pushed the "now is the time" point always a bit further once I had reached my initial goal. And I was really burnt out from my job - my body showed me with persistent gut issues over several months, that have now cleared up as well.
