Don't hang your hat higher than you can reach

Don't call the alligator big mouth till you have crossed the river

If you make yourself into a doormat, people will wipe their feet on you

We'll hang you out to dry

The one thing they could tell me they could hang their hat on was, they had never fired a coach. They had always let him finish out his contract. It's very interesting that the next coach they hired, they didn't allow that to happen.

Take off your hat to your yesterdays; take off your coat for your tomorrows
