If we see the person we were before was not who we would be happy to be again, then yes to recreate ourselves to a person we would like to be would be awesome. Wouldn't be wonderful to go back in time and create the person we think we would be happy to be? Would we know what that was really?

Like the Zebra, born with stripes, stripes to the skin, but would rather be golden and glowing when they have the most beautiful coat anyway.
Like people who have straight hair want curly hair, people with curly hair want straight hair. Does it really have anything to do with the hair though? Could it be that personality of the person with straight or curly hair that makes that hair style so attractive? Their achievements? Does the hair or fur really matter? Is it more about self acceptance? Maybe we can tweak somethings to make us better people, but that doesn't erase the past or memories, so it will be a constant monitoring of self until those behaviors become more naturally. No one is perfect, or are they?
