Upbeat people make us feel appreciated, important, and fantastic. These are the folks who expand and warm us with their positive energy.

The Broaden-and-Build Theory in Positive Psychology suggests that positive emotions initiate upward spirals of positivity which contribute to our optimal well-being. It is no wonder positive people are more likely to make a positive impact!

People who cast a negative energy can make us feel doubtful, devalued, and disrespected. In response, we contract and are left cold as our awesome energy evaporates in their shadow. Downward emotional spirals ensue.

A light-hearted point to consider: Do you know the number one reason a man falls in love with a woman? Because of how she makes him feel about himself. Do you know the number one reason a man falls out of love with a woman? Because of how she makes him feel about himself! It is the same reason! When you inspire and motivate another person through your positive energy, they want you to stick around!

How we feel with someone—if they improve our mood or cause our heart to sink—can determine the health of the relationship. How do you feel around them? It's a simple measurement tool.

Throughout your life you will meet thousands of people, but every once in a while, you feel instant chemistry with a person and connect immediately. It is like meeting an old friend or returning home again. Your relationship enjoys easy compatibility and commonality. Not only can you sometimes finish each other’s sentences, but regardless of how much time may pass, you can reunite and start up wherever you left off.

Instant chemistry feels great! It is a raw, organic emotion. The art and science of relationship chemistry is still a mystery to me, but it is always a delight when it happens. You certainly know when you feel it, and that sizzle begins many a new relationship.

Ask anyone who has ever fallen in love at first sight and they will tell you—their mutual chemistry created an instant attraction. We have all known friends who went on a first date and knew instantly that they would spend the rest of their life with that person. Or, they knew instantly there was no chance because there was no chemistry at all.

Is chemistry a biological reaction which supports the propagation of our species? Or is it simply about being excited to find someone with mutually shared values, passions, interests, or experiences? Or is it because you have the same energy, vibrate at the same frequency, or share the same attitude? Regardless of how it happens, a robust and healthy chemistry is always a nice surprise and something to be celebrated.
