Love this! I know that when I teach or tutor someone, especially if it is something I've never taught before, that very act helps crystalize the subject in my head. There's something powerful about putting thoughts into words. It's like doing so helps cement the realness of the thought. I love the word realize. At first glance it means "to understand." But on further observation, it can also mean, "to make real."

In regards to focusing on your strengths, for me personally, learning my Myers-Brigg personality typology really helped me to understand what I can best contribute, but also negative tendencies I can curb if I observe myself vigilantly.
