depends if you’re just looking for a fresh start or if you’re running from something and how much you care about the people involved.
if I just wanted a fresh start, I’d pull together as much money as possible quit my job and move to someplace that caught my eye and gave me a good gut feeling.
If you’re running it’s a lot more complex, you need to do as much as possible to erase yourself, credit cards, name, registrations, contacts, etc. all of it needs to go.
Don’t forget the people though, if you really and truly cut all ties suddenly and without (and maybe even with) explanation many may not understand and will resent you for it, possibly forever.
In the end though, it’s really your personal habits, thought processes, and decisions that need to be adjusted. Because those are what you most create your environment. A lot of people “run” from circumstances without realizing that they themselves are the reason those circumstances exist only to find themselves in the same situation months or years later.
