A simple way to reframe resetting your life: Don’t let the words “starting over” intimidate you. You’re not really back at zero. You’ve lived. You’ve tried things. You’ve seen some stuff. Use it. Start fresh, but with better eyes. Past mistakes are an edge, not a disadvantage.

I think the core of this is all about the lens through which you view your current position. View it as "starting from scratch", and it'll feel that way. View at "starting from experience", and it's an entirely different mindset.
