Should I change my last name to my mother's maiden one?

My father has never been a part of my life and I have not ever been associated with him. My grandfather has been a surrogate father my whole life and my mother's part of my family has been there for me all the time, but my father's side has been nonexistent. I do not want to take my step-father's name since I don't like the name and find his side of the family not to my liking. So, I was wondering if it would be a good idea to change my name to my mother's maiden name. Should I?
