I remember one topic we are taught in school then "Epistemology" and after the course there is a saying that " be true to yourself" and then I realized that if your not true to yourself then you can't be true to others.
If we can't identify that we are wrong, or lazy then things will be hard for us at times and not only alone, it will affect you physically and phycologically and also at your work place.

Thanks for sharing.
