Here are my top five.
Your Top Strength
Humor and playfulness
You like to laugh and tease. Bringing smiles to other people is important to you. You try to see the light side of all situations.
Your Second Strength
Love of learning
You love learning new things, whether in a class or on your own. You have always loved school, reading, and museums-anywhere and everywhere there is an opportunity to learn.
Your Third Strength
Curiosity and interest in the world
You are curious about everything. You are always asking questions, and you find all subjects and topics fascinating. You like exploration and discovery.
Your Fourth Strength
Creativity, ingenuity, and originality
Thinking of new ways to do things is a crucial part of who you are. You are never content with doing something the conventional way if a better way is possible.
Your Fifth Strength
You are aware of the motives and feelings of other people. You know what to do to fit in to different social situations, and you know what to do to put others at ease.
