sounds like interesting homework. your example to choose from re trust. i felt like is a blanket statement like either black or white. it said someone, not all. so this is more the grey area statement which i view as healthy. if we trusted everyone we would not do so well in this world, imo.(black) on the other hand it's important to have trusting relationships. (grey) that is a positive statement.
i'm i on the right track?
i had a tendancy to view the world as either bad, black, or good, white. those extreme views made me unable to be tolerant in some cases and too approving in other cases. i still have to keep an eye on me, lol, cause it's easy to slide back into old beliefs-black/white, glass half full vs. glass half empty.
hope this helps.
