Know right from wrong. Reading is one of the great pleasures of life and if you have a book, you'll never get bored, be alone or lonely. You'll also learn a lot about the world around you. While an apple a day may keep the doctor away, a generous number of hugs a day will keep a smile on your pretty face. Beware of people who don't or can't hug.
People come in all colors, shapes and sizes, both physically and emotionally.
Accept them as they are, not as you might like them to be. Learn to listen. What other people have to say is just as important as what you have to say. Also, if you are a good listener people will think you are a brilliant conversationalist. Be it a little or a lot, share what you have with others.
