In another lifetime

Do you believe in another lifetime? I just turned 32 and I haven't thought about my next lifetime for a few years....until someone brought it up to me the other day. I used to believe that there are old souls and new, that you had the opportunity to repair the past in the future, but why not repair the past in the current? I speak from first hand experience when I say that I have done many things in the past that I would change but how far do you go? I have spent the last year of my life trying to make amends with those I felt I have done wrong. I get very caught up in emotions and am extremely idealistic. I kind of feel like "Earl" apologizing to people that have no idea what I am even referring to. It makes me realize how self-consumed we are as human beings. We all have our own concept of reality and the same story can resonate completely differently from party to party. So far as my next life...this one has been pretty good to me. I often think there are things I would change if I could wiggle my nose and do so, but if there wasn't heartache, how enjoyable would the good times be? Enjoy the moment..........
