Researchers have found that gratitude correlates with better mood and sleep, higher confidence, and lower fatigue and inflammation. Don't have anything to be thankful for? Start with electricity, running water and roof over your head.

Give someone your spot in line, buy a co-worker his favorite morning drink, or call your mother and mindfully listen to her tell you about her week. Even little things can make a big difference in someone's day. Plus, researchers have found that performing acts of kindness make people feel happier.

You can't be present and your best self if you’re constantly asking yourself questions such as: Did they think that I was smart? Did they think that I was successful? Did they think what I said was stupid? In truth, you can never really know what someone else thinks of you. So, instead of worrying about it, be your most confident self and concentrate on what you want to communicate, ask good questions and look people in the eyes.

Think about the people you miss the most on this planet. Chances are, they were interested in other people’s lives, generous and set a good example. Work now to be someone who makes a positive impression.
