Even according to the law of the mind it is not possible that you keep thinking selfishly, continue being biased, and keep living with negative feelings and despite that, your confidence, concentration, intelligence and foresight to go on increasing. No, this can never happen! On the other hand, you already know how important concentration and confidence etc. are in order to improve life. You are smart enough to understand the rest. Therefore, it is not necessary to explain to you in detail the importance of thinking selflessly and having positive feelings in life.
