Most people are making a relationship with others. Also, they change their images to keep the relationship depending on the situation. The image might be different with themselves than they thought because the image can convey a different meaning. To reduce the gap, you need an objective assessment. However, people tend to pack or disregard themselves. So, it is hard to make a right judgement by yourself.
On the other hand, fortunately, I experienced that I was able to meet myself through a person who are similar with my attitude and character even I did not realize. I was surprised and embarrassed whenever I face him. However, It makes me that I can judge myself objectively as well as reflect on myself. Although the project is to know me through others, it might be an opportunity someone who want to know himself.
