Levitation's not for everyone.

It usually takes a long time to learn and although floating is mostly enjoyable, on occasion it can actually be quite uncomfortable.

The time to start learning is during childhood. I don't know of anyone who started after the age of 6.

That's not to say that anyone actually got off the ground at such an early age... it's just that you have to start the process early.

I think it has to do with the way a kid thinks about things.
