The power of money and time.

Okay, Elly already took my idea, so I'll come up with another one: super-intelligence. With it comes the ability to understand the world, to create fantastic and fantastical new things to benefit the human race, and to generally progress the world so that it is better for everybody. I also think that an extremely high intelligence can make a person very understanding of others' thoughts, feelings, and opinions (I'm talking superpower-level, polymath-type genius; of course we all know smart people who are callous twats). With that, you could benefit and support the people you love and care about, too.
