Everything happens for a reason. The direction of our lives, the path we choose, the people we let in or out, the decisions we make, are all done with a sense of purpose.
There will be times where we will find success or accomplishment. There will also be times where we will fail. What's important is that you come away from incidents that make you particularly happy or sad, with an understanding.
The understanding is that every experience we have, especially the ones that stand out in our minds, are to teach us something. Try to figure out what the lesson is, absorb it and move on.
Make the effort to stay healthy, in mind and body. Focus on what you have, strengths and weaknesses, that contribute to your life and the lives of those around you. Be conscious of your actions and deeds; treat those around you as you would like to be treated.
The forces of nature, the higher power, whatever they may be, are at work. Pay attention, but follow along...with love...
