Though our styles are not exactly the same, I share the sentiment my daughter Diana expresses in one of her most recent Tumblr posts:

There’s no better feeling than making a difference. But because the type of difference I’m best at making comes through quiet observation and subtly shifting people’s minds, I rarely get the honor of knowing what changes happen as a result. I can feel the warm glow of a lightbulb turning on in conversation, but I don’t usually get to see down the whole corridor it illuminates.

Once in a blue moon, though, I catch a glimpse of the bend in the hallway. Those are the very best days.
