What would it be and how would you use it?
Telekinesis - I'd silence the minds of stupid people
If you're thirsty, refill your cup
Lonely, fill your bed with your favorite celebrity
Someone is being an ass, refill their bladder
Invisibility...id use it for my own sanity
Super Speed and strength
Flying, I would travel everywhere.
Teleportation! I could travel the world for free ^_^
Control time! So I can do things one at a time. And to sleep like forever. And workout. And play games. And lastly make everyone's 24 hours a day a 5000 hours a day to me.
Understanding the mind of all creatures(telekinesis) Or controlling plants or being able to change form at will.
The power to heal everyone
I would love to read people's minds.
