It sounds simple and it is. Smile. Smiling is an incredible key to success in just about anything you choose to do. For some of us smiling comes naturally. For the rest of us, due to being shy or overly self-conscious, smiling is a challenge. Think about this. If a person smiles at you, are you more or less likely to interact with them? Or, conversely, if a person scowls at you, are you more or less likely to interact with them? Okay, not everyone you smile at is going to smile back. And, no doubt, there are those individuals who, because of their own shyness, might be put off by anything other than a neutral look on your face. However, by and large, if you smile when you interact with people they are going to be put at ease and feel comfortable in your company. In fact, simply smiling at folks will likely increase your likeability. We like doing business with people we like. We date people we like. We want to be around people we like. We associate with people we like. No one enjoys working with someone grumpy.
