Never let anyone convince you of anything negative about yourself unless it is for your own betterment. And, if what they have said is true, then thank them and take it in for consideration. But unless someone is trying to help you, don't you dare, ever let anyone tell you who and what you are, because, on this planet, you are the unquestionable and supreme authority on — you. But it can be useful to ask yourself a few important questions. If you met your exact self as another person, would you like them? Would they be a good friend? Would they seem kind, generous and loving? Would they have time and patience, and invest in your friendship? Would you feel good in their presence? Would they make you laugh? Would you truly want to spend time with them? Would they be a good influence? Remember, no one on earth spends more time with you, than — you. Be a good friend to yourself. The best way to be a good friend to yourself is to be a good person. Be the kind of person you wish you had in your life, because who you are, is exactly who you've got.
