If you have trouble accepting or forgiving your past self, it might be tempting to just ignore it or run away from it. But interestingly, we have no issues discussing, forgiving, and even empathizing with someone else’s difficult past. So why not do that with our own past?
See your past self as someone else’s life. You’ve obviously changed a lot over the years so it shouldn’t be that difficult or unreasonable. And once you’ve severed the connection between your present self and your past self, it becomes a lot easier to think about the past without getting too emotional or feeling excessive regret.
