Excerpt:

1. Invitation

Take a chance and try my fare:
It will grow on you, I swear;
Soon it will taste good to you.
If by then you should want more,
All the things I’ve done before
Will inspire things quite new.

2. My Happiness

Since I grew tired of the chase
And search, I learned to find;
And since the wind blows in my face,
I sail with every wind.
