no, I don't think so! We become... ourselves!! I think every relation we have make us different, including our mother, but we are definitely not them; we have some of their qualities, some of their default but many other thing make us who we are. And that said, we can change what we don't like about ourselves... we just have to identify it first and be ready to work on it (sound so easy written this way... I should re-read myself sometimes

)
It's both an interesting and hard assignment; you could sure discover some interesting things!
Take care
