Positive thinking is a catch-all phrase, but in reality, being mindful about your language and your outward emotions can have a stellar inward effect, according to a paper published by the National Center for Biotechnology Information. Broaden your outlook, cultivate empathy, fight negative thoughts. Give a little extra, proffer a genuine compliment, remember your manners, volunteer, forgive, overlook pettiness, and you will be amazed at the shift in your life and outlook. As a bonus, people will likely be drawn to you, inspired by your outward actions and demeanor. Like negativity, positivity is contagious.
