I think everyone should read this quote by John Wooden (greatest coach ever).
People are going to say all kinds of things about your reputation throughout your life and there is nothing that you can do about it but you can do something about your character.
The definition of character:
1.The mental and moral qualities to an individual.
2.The distinctive nature of something.
Hold fast to your mental and moral qualities because ultimately this is who you are as a human being.
