It is the end of the day and I am tired. My mind is full and my body is aching. Before I go to bed I need to clear my head. What happened today? What did I do wrong? What did I do right? What could I have done better? (I was stressed because of my bosses' behaviour. I had a nice conversation with a friend. I should use the phrase, "we will see" more often, instead of answering directly something that I would later regret.)
If you do this every day, you are avoiding being a robot, because you think about yourself, about your reactions and your choices. In the end, you are learning yourself. You wouldn't imagine what kind of personal satisfaction is this....to get to know yourself a little more day by day.
