In my youth my grandfather and father would sit me down from time to time to share a pertinent piece of advice that suited whatever situation was at hand or to bestow upon me a bit of wisdom that they had either learned in their life or had been bestowed upon them by the men in their family. If I were to give just one piece of advice to everyone in the new year it would be a motto I live my life by, and that is "Be Mindful."
Be mindful of what you do, what you say, how you act and how you treat people. Be mindful of others. Be mindful that what you do affects others. Be mindful to not let others adversely influence or affect you. Be mindful that at the end of the day you are responsible for the things you do. Most importantly, be mindful of your passions, ideals and happiness.
