[prtk]

You can teach kids programming. If they learn to make small games their parents might pay you some money.

And material you create while teaching kids can later be converted into book form and published.

I wrote KTurtle[1] to basically learn 'real' programming :)

I had only toyed around before that.

Anyway, I think prtk is right: there is a lot to be picked up in education. And as always; make yourself cheap enough to build portfolio at first.
