I can do anything

I can do anything I want.
I can write a book.
I can fly a plane.
I can sail around the world.
I can be the best teacher in the world.
I can build furniture.
I can write poems.
I can play the guitar.
I can play a hand drum.
I can cook like mad.
I can live in France.
I can build a chateau.
I can make great beer.
I can cycle everywhere.
I can scuba in the South Pacific.
I can take world class photos.
I can live all my dreams.

So why don't I?
