Reputation: overall quality or character as seen or judged by people in general, as told by Merriam-Webster dictionary.
Growing up as a kid, parents always emphasized that your actions matter. Your actions matter in the household, in a school setting, on the field, in a grocery store, everywhere. Not only because they affect other people, but because someone is always watching. Your character is always being noticed. Hence, the emphasis on the need for originality - your originality is what allows you to stand apart from others.
As a young kid those phrases may have seemed redundant from your teacher telling you, to your athletic coach, and then from your parents. Although, as a kid you know nothing better than to be yourself.
Growing out of childhood times is when people start to lose their originality and get wrapped up about their so-called reputation.
