The meaning we choose to give to our circumstances and the events of our life determines the outcome and experience we receive from them.
We can literally decide the meaning we give to the experiences, people, places, and coincidences we encounter in our everyday life. We can choose to view circumstances in a way that best serves us (and ideally, society as a whole). Or we can choose to view them in a way that holds us back and limits us.
Once you realize that life happens THROUGH you, not TO you, and that every experience you have is an opportunity to learn more about yourself and others, life becomes much more enjoyable and much less stressful.
