How can you be rejected from something good?

Good can only be found within ourselves and others, not in things.

If you were rejected by what you consider to be a good person, then, knowing that person is good, they rejected you for good reasons, and there should be no qualms. Or, if they were not a good person in your consideration, you can safely disregard any harm you thought was subjected upon you being rejected.

Been the story of my life. Still waiting, though, for the last 'rejection' to come to a good fruition.

positive attitude always helps (and you seem to have it)
