"Show me what a man envies the least in others and I will show you what he has got the most of himself." -- Josh Billings
It's a little disconcerting to discover that the faults we deplore in others are exactly the ones we're dealing with too. A person who berates a partner, friend, or co-worker for being too critical is demonstrating the same flaw. Why can't we see our own character flaws, so apparent to others?
Maybe it's because we're dealing with a spiritual principle. Our brothers and sisters are our mirrors. God made us essentially alike. Each of us is as deserving of criticism as anyone, and as worthy of love. When we condemn someone, we condemn ourselves. By loving others, we are loved.
Today I will see others as I want to be seen, and treat them as I want to be treated.
