Secret Super Power: Connectedness. I build bridges between people and groups. I help others find meaning and value by looking at the bigger picture of the world around them and give them a sense of comfort, stability, and optimism in the face of uncertainty. Strengthening the bonds between me, the people I know, and even those I will never meet gives my life meaning.
