Can anyone describe this simple quote?

Question

If possible, what is an example?

"Remember that what you believe will depend very much on what you are"

Answer 1

IMO, it means you tend to think every one/thing is like you for eg if u are a bad person you think ppl most ppl are bad and the world is a bad place. If  u r a positive , energetic and loving person you see the world as a beautiful and bright place with a lot of nice ppl thus u expect good things.
