This is probably some of the truest words ever.
"We are never too important to be nice to other people."
I have seen it too many times when people how people we used to know either moves up in their career, our come into some money.
They start acting as it they are more important than everyone else, or like others are beneath them.
This makes them seem foolish and arrogant or just plain stuck up.
Guess what when you eventually come back to earth, you might need those same people you treated unkind. Because of your unkind attitude against them, they might want nothing to do with you.
This is why we always have to be kind to people and treat them with respect.
