People all have strengths and weaknesses in life. To find them is the important part. We all know what we're good at but we need help improving what we're not good at. Character could be an area of weakness or strength. For example, if you have a confident character, you could not be easily swayed to peer pressure but you might run into problems too confidently and naive.
All you have to do is ask questions and help others solve the questions they have asked as well. Answering questions is how you earn points, which make it so you can ask people questions and reward them for their answers.
