It is natural for people to want to get better, but how can one measure and see changes in themselves? It's difficult to improve what cannot be measured. A diary of observations of your thoughts, actions and personality traits can help with this. Every decision, action, or thought we have is a manifestation of our qualities, and vice versa, our actions and thoughts can shape our qualities. Recording the manifestations of your qualities, you improve your self-analysis skills. This will help you to manage your qualities more consciously.
