When did you decide it was time for a new adventure in your life?

I'm not asking for advice. I am simply interested in your life stories about when you decided that it was time to shake up your life a bit.

Was it because you wanted to be in X job but felt scared to leave Y job, be it for financial stability or otherwise?

Did you consciously decide to overcome any fear (of flying, of heights etc)?

Did you move across the country or world for a SO - did it or did it not work out?
