When there is respect for others there is actually an environment that is created in which they can strengthen themselves and grow. The one who has this elevated consciousness is not caught up with others'weaknesses. On the other hand, he is able to encourage them to use their specialties.
When I see someone working with his weakness, I need to think of one speciality in that person and relate to him with this speciality. Also I need to draw his attention to it and slowly I'll find him getting stronger.
