6. 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.
7. Have a positive outlook and attitude. Who wants to be around people who are negative, complain a lot, or have nothing good to say? In fact, most of us run when we see them coming. Instead, be the kind of upbeat person who lights up a room with your energy when you enter it. Do it by looking for the best in people and things. Smile warmly, spread good cheer, and enliven others with your presence.
8. 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.
9. Be supportive of others. Being supportive is probably the most endearing quality you can integrate into your personality. Just as you yourself welcome it, be the support for others when they need it. We all love a cheerleader in our corner; someone who is encouraging, believes in us and helps pick us up when we're down.
10. 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.
