This was a question Jesus asked His disciples. Jesus was not seeking personal understanding, He was seeking understanding for His disciples.
In hopes of finding out who we are, we should be asking this question of others to get better enlightenment. Others see things we do not see. Others perceive things differently. So why not ask how others perceive you?
That is the challenge of the day. Ask at least one person to list 1 area they perceive you to be skilled in and 1 area you are needing to work on.
