No ,specially the name wouldn't affect one's life. Appearance could affect one's life, it depends if one chooses to rely on their appearance,it might help in joining certain activities or pursuing specific careers.

I don't think so. This may sound too cliche, but it's what's within that matters. Yes, looks may matter at first, especially when people aren't given the opportunity to know others more. We don't have all the time in the world and surely we cannot get to know others deeper. So with no other background information or something, we only get to see their looks and appearances. And that's where we base our first impressions of people. But as I said, things will eventually change once we know people better. More often than not, what's inside is much different than physical appearance; And from there, we get a deeper understanding and can form a better opinion on people based on their behavior and attitude, opinions and beliefs, intelligence and wit, and others.

No not! cowboy...

Yes... just look at movie stars. Many of their names you see in public are stage names; totally different from their birth names.
