Wise advice. The only thing I'd add is that it's probably not in your best interests to judge those who are loose with their word. Notice it & remember it but try not to judge them for it. This is the distinction between discernment & judgement. We're all on a journey & we don't know why people act the way that they act. We just can't make that assumption & doing so doesn't help us on our own journey. It also doesn't mean that you should trust them with anything significant either.
