There are people in this world who are genuine enough to pay attention to their own behavior. Those who are aware that how their words, actions and thoughts have an impact on those they interact with.
Here is a small list to read at the end of the day to see if you want to change or develop some of your behavior. Pick no more than two or three at a time.
Was I free from anger and judgement?
Did I give anyone sorrow or take any sorrow?
How much negative thinking was I wrapped up in?
Was I stable or unstable.
What did I bring into my interactions today? Was I positive?
Did I respect everyone regardless of name and fame?
Did I take a moment here and there to reflect on what I was thinking.
You can add more suggestions to the list. You can make a chart to fill out at the end of the day. Either way your behavior is so much more dynamic than you realize.
So be positive and joyful.
