That's true! In life it's best we try to understand why some persons are acting in a particular kind of way, knowing what causes these characters, knowing if these characters are desirable and then going towards advising that person, changing his or her mind by knowing what they're wrong about. By doing this you can be able to explain to that person, giving good ideals and giving advise on areas he can improve more exhibiting characters and attitudes that are desirable to other people and also the society. That's good i think the best thing i have learnt from here is knowing people's fault before trying to correct them, in this way you can be able to determine specific areas that needs improvement in their life style and also being able to change their mind and attitude positively.
