We do not actually know other people; we only know our judgements.
Do not believe the road signs. There is no one way. If it's your truth, then it's the right way. Trust your instincts!
You have to accept that you'll never be good enough for some people. Whether that is going to be your problem or theirs is up to you.
You set the standard for how people will treat and regard you, by how you treat and regard yourself.
Life is so big. Do not try to fill it. Instead, expand within. You are enough for you.
