If I had superman's abilities, I would go around and do whatever I wanted whenever I felt like it.
I would just walk out in the middle of the street and stand there and let a bus slam into me and crush up.
Then I'd flick people who would try to fight me.
I'd just do things like pick up a car with one hand and throw it several miles like it was a baseball or something.
I'd just probably go mad with power. I'd probably take over the earth.
I'd use my light speed and fly around the space trying to find other signs of life since scientists are always disputing over whether aliens exist, then they could shut the f#@k up about it.
I'm glad I'm me cause I'd go insane with powers like that.
