My POV is before we can change, we first go through the process of grieving our mistakes. Only after facing our grief about those missed opportunities can we begin to change but it happens way too slowly. One baby step forward, three back--it takes a lot of awareness and "tries at bat" to be a little bit more like the kind of person we aspire to be. Then you put together some very good days only to have a "...Terrible, Horrible, No Good Very Bad Day" (remember that book?). Acceptance, acceptance, I try to live and let live but there are days when I don't. Maybe everyone struggles with this but you are just more aware of it now.
