To what degree do you believe your given name has influenced who you are?

Do you believe people would treat you differently if your name were Jack as opposed to Ted, for example, or Sarah as compared with Mary? How much does a name define who we are? I think it's safe to say that some names (e.g. Adolph, Osama) are so infamous that they stereotype everyone else who bears that name.

People whom I've met briefly and then not seen again for days or weeks have mistakenly called me Michael, but I have two cousins named Michael and they look nothing alike nor anything like me. My name is T------. Also, while I have a Spanish surname, it's NOT Martinez, yet I've been called "Mr. Martinez" more than I can remember. For the record, my last name begins with an "H" and ends with a "z." I cannot explain this occurrence, but it's happened so often that I've come to expect it when meeting people.

Do you like your name? Have you ever wanted to change it? If you could choose a new name, what would you call yourself? Do you think people would treat you differently?
