Knowing a person's strengths and weaknesses

Today was another great day at Vari Hall. I was very satisfied with how everyone was working together with approaching students. One thing I learned is that each person is unique, including myself, with their own sets of strengths and weaknesses. To answer my question from yesterday, I believe that I should praise and build up my members' strengths while pointing out improvements for their weaknesses as well. I agree with Jerry that each person is good at something. Our role is to find out what that is and help each of our members excel in those areas. I wonder what else I could do?
