The ability to make any substance = free money
Mind control = Power & Sex
Time travel = Able to get next gen tech
Reasons I didn't chose some stuff:
Flying: What benefit would this give? You would just freeze to death in the cold air and even if you wore clothes, the ascent is so fast that if you actually wanted to gain serious height, you would faint from lack of oxygen = splat
Invisible: Why be invisible if you can just convince everybody around you that you don't exist. Mind control has more uses and you don't get thermo-detected.
Immortality: At some point, either the human race will die, or evolve into something else. Keeping up with the times will be pretty difficult and after the next mass extinction, very boring as well (Cue hitchhiker's guide to the galaxy)
Stop time: As you may know, the air is made up of small molecules that move around you. By definition + Relativity, stopping time is the same as stopping the movement of all molecules, and making it so they cannot be started again for the duration of the time-stop
Therefore the air will freeze up around you and inside you and you will be unable to breath or move, because it will be holding you down as if you were placed in a giant steel one-piece
You would be able to move through space I guess, if you excepted the giant hole where your lungs used to be.
Making bubbles of non-time freeze would be like flushing the universe down the toilet.
Super Human athleticism: Exepting the fact that I rarely move and would have no use for it, you would constantly have to eat to feed your giant metabolism else you die. The food costs would soon skyrocket.
