Make sure to look for VIA Survey of Character Strengths, and you'll need to create an account in order to do the survey. There are other surveys in there around optimism, authentic happiness, meaning in life, etc. All quite interesting!
Turns out my strengths are:
Your Top Strength
Forgiveness and mercy -
You forgive those who have done you wrong. You always give people a second chance. Your guiding principle is mercy and not revenge.

You excel at the tasks of leadership: encouraging a group to get things done and preserving harmony within the group by making everyone feel included. You do a good job organizing activities and seeing that they happen.
Strength #3

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.
Strength #4

Strength #5
