The best words I every heard were be true to you
be yourself
that's all you can do
there's no point in being someone else

Second best words I ever heard is just one word
that word is no
no no no
you cant ever be afraid to just say no
let no one guilt you to utter the other word

Third best words I ever heard are just two words
speak out loud
ask the question
speak your mind
don't be afraid to just speak..
