Answer:
Well my first choice would be Infinite knowledge or in other words wisdom. I would like to be the smartest person alive. Solve problems no one has solved and help the world by coming up with the best ideas for tech and health. Help with Global Warming, Cancer, and improvements for the human body. And also, I be like Sherlock Holmes.
My second choice would be mind reading. If I had mind reading powers I would be able to know how people feel. Like if they're depressed about something in specific, I would use my Wisdom power to come up with a solution to the person's problem. I could help with people with suicidal thoughts. I would also read an animal's mind on how they feel about humans and what they think we should change or fix.
For power number 3 I would choose teletransportation. Useful, If I see in TV someone's about to do something and die I just go there and help. If someone throws themselves from a building I'll be there. If someone really needs a fast delivery I'll be the man. I myself won't be in a rush, And I'll never be late for duty. I would also teleport from planet to planet around space, to clarify doubts about space.
