Knowing that something or someone is wrong doesn't give you the right to criticize. Use your advantageous position to help, not to dismiss and destroy.
--
It doesn’t matter if you’re right or wrong,
it doesn’t even matter if the others are wrong or not,
it’s irrelevant that you know how to do things in a better way!
Of course you know more,
of course, everyone else may be wrong...
but that's no reason
to be always criticizing,
pointing out the mistakes,
lowering the mood,
& destroying trust.
Try to support,
cooperate, to give your best,
and be supportive.
