When we think of someone that has a "good personality" we think that they are likeable, interesting and pleasant to be with. Everyone wants to be attractive to others. To that end, having a good personality is vital - probably even more so than good looks.
In fact, approximately 85 percent of your success and happiness will be a result of how well you interact with others. Ultimately, it is your personality that determines whether people are attracted to, or shy away from you.

What you can do to improve your personality:

1. Be a better listener

Jacqueline Kennedy Onassis was considered one of the most charming women in the world because she cultivated the skill of being an exceptional listener. She was known for the way she would look a person in the eyes, hang on their every word, and make them feel important. There is nothing more appealing than having someone listen to you intently making you feel like you're the only person in the world.

2. Be a good conversationalist

This relates to how much you read and know. Once you have much to contribute, learn how to talk about it with others. No one can read about or know everything, so it's refreshing to learn from others those things we don't have the time to about read ourselves. If you happen to be shy, join a group like Toastmasters that encourages you to talk about what you know.

3. Have an Opinion

There is nothing more tiresome than trying to talk to someone who has no opinion on anything. A conversation has nowhere to go if you have nothing to expound on. If, however, you have an uncommon point of view or differing opinion, you are more interesting and stimulating to be with socially (unless you're a know-it-all, of course). A unique outlook expands everyone's perspective.

4. Be yourself

The next most tiresome thing after having no opinions is trying to be something you're not. Molding yourself in order to fit in, or be accepted, usually backfires. Since each of us is unique, expressing that uniqueness is what makes us interesting. Attempting to be a carbon copy of someone else not only falls flat, but reveals a lack of authenticity.

5. Be fun and see the humorous side of life

Everyone enjoys the company of someone who makes them laugh, or smile, so look for the humorous, quirky side in a situation - there always is one. Comic relief is a much welcome and needed diversion at times. When you can add fun and lightheartedness to an otherwise dull or gloomy setting, others will naturally be attracted to you, not to mention grateful.

6. Have Integrity and treat people with respect

Being honest and true to your word will bring you the admiration, respect and gratitude of others. Nothing improves a person's personality more than integrity and respect - respect for others, as well as respect for yourself.

We humans have the power and ability to shape our personalities however we wish. When we develop ourselves to be all that we can be, we contribute to our own, as well as the happiness of others.

On a related note, having a pleasant, engaging personality is significantly related to Emotional Intelligence (EI or EQ). Those of us possessing high EI invariably have great personalites.
