Found some more sayings from 'Life's Little Instruction Book' (which was one of my dad's favorite little books that he gave away as gifts).
Whenever you hear an ambulance siren, say a prayer for the person inside.
Hold a child's hand when crossing the street.
Don't forget that a couple of words of praise or encouragement can make someone's day.
Remember that a minute of anger denies you sixty seconds of happiness.
On your birthday, send your mom a thank-you card.
Never criticize your country when travelling abroad.
When you hear a kind word spoken about a friend, tell him so.
When loved ones drive away, watch until you can no longer see the car.
Keep a backup copy of your personal address and telephone book.
Never buy a coffee table you can't put your feet on.
Say something positive as early as possible every day.
Regardless of the situation, remember that nothing is ever lost by courtesy.
When staying at a hotel or motel, don't accept a room next to the ice or vending machines.

Never go near a kid who's holding a water hose unless you want to get wet.
Never refuse a holiday dessert.
On your birthday, send your mom a thank-you card.
I have done this for years. Not a thank-you card, usually a pretty yellow rose in a vase. I know that my birthday is a special day for her, because my son's birthday is a special day for me. :-)
Never buy a coffee table you can't put your feet on.
I like this one too.
