When you talk about changing your "self" you are talking about changing something that transcends time, space and material limitations. How can you change your soul or spirit? How can you ever change who you are as a person? Your essence?

On the other hand, your likes and dislikes and personality does and can change over time! Every atom in your body changes every 6-12 months and if you compare yourself to who you were 10 years ago you might even say that EVERYTHiNG about you has changed

Is the thing that you call "me" or "I" simply just a mental construct? In that case, does it even really exist or are you simply a bunch of mental words and labels? 

Whatever you are, is it possible to change what you are in order to enhance your experience? How do you go about becoming a "better" you?
