If I could have any power I wanted, I would choose the power of creativity. To be able to create anything I wanted or saw fit to make, with but a single thought.
Why?
I could create enough food to feed everyone on this earth.
I could erase pollution as if it never existed.
I could bring back extinct species that have died due to our actions and presence In the world.
I could heal any wound, injury, disability or disease to ever effect anyone. So that no one would suffer again, from the loss or hardships of a loved one.
And most importantly... to be able to create the opportunity for everyone to finally get along, and exist side by side, no matter what creed, gender, religion/belief or status. To finally bring an end to violence and war, and bring about peace on Earth.
