It doesn't make me unhappy that I "can't" be president, because I could, I'm just not old enough yet.

Maybe I'm just being naive,but I think a woman president will come, I don't know when but I don't think it's TOO far away ( no, not necessarily Hilary) I would venture to say a minority man will be presidet before a woman though.
I know which way to turn to tighten or loosen a bolt without stopping to think but this does not increase or decrease my level of general happiness.
Having only one pair of shoes, one color for all seasons would make me sad, not increase my happiness
