Gain A Quality Or An Ability

If you could wake up tomorrow having gained one quality or ability, what would it be?

We decided to work are a team. The Beloved is going to become super intelligent, and I am going to be able to communicate effectively to all.

I did consider becoming a teleporter, and setting up my own SuperUber personal transport service. I could become fantastically rich if I was able to teleport, and there's so much good that could be done with this ability.
