A friendship poem:

It's true. You can tell a person by the company she keeps. Our friendships not only tell a lot about who we are -- they make us who we are.

The friendship poem above says it all. You will know a friendship is true when it brings out the best in you.

Take a look at your friendships. Do they bring out the best in you? That might seem like a silly question. We all tend to think, "Of course they bring out the best in me. I wouldn't be friends with them otherwise."

But stop and think why you are friends. Here are a few common reasons why people become friends:

• Common background, sharing a comfort level in company from "the same side of the tracks".

• Common current situation, being able to discuss parenting, home renovations, or some other major life circumstance.

• Common interest, such as cards, bowling, hunting, etc.

• For shy people, a person who actually approached you is a candidate for friendship.

• For leaders, somebody who seems content to follow is a likely candidate.

• Somebody you spend time with anyway, such as a colleague, sibling, etc, often becomes a friend.

• Somebody you see frequently anyway, such as a neighbor, store clerk, etc, could become a friend.

These are just a few reasons people choose friends. It is the easy, natural way, but it is not always in our best interest. Sure, we should always want to get along with colleagues, neighbors, siblings, and anybody else.

But we should choose our friends, the people we open up to, very carefully. For instance, even a sibling can bring you down, pooh-pooh your dreams and load you up with negativity. "Ha! You think you can teach? What do you know about teaching?"

Even well-meaning friends can be dream-slashers. "Oh, do you really think you should go into business for yourself? I mean, what about security?"

On the other hand, some friends have a way of building up your dreams. "Go for it! You could really do well. And at worst, you'll at least have given it your best shot!"

Friends will often lend a hand. "Gee, I don't know much about fitness, but is there any way I can help you reach your goal?" Dream-slashers usually don't. "Hey, if you insist on pursuing this crazy scheme, leave me out of it."

A true friendship should:

• Encourage you to live your dream.

• Support you toward your goals.

• Sympathize for your losses and help you find a silver lining.

• Build your self-esteem.

If happiness and life-satisfaction are your goals, your friends should be chosen on the basis of how well they can accomplish those four goals.

Happiness is a personal choice that comes from within. But it sure doesn't hurt to have supportive friendships that help us achieve our goals.
