I’m Learning To Play the Piano Today

I’m learning to play the piano today.
Tomorrow I’ll learn the guitar.
The day after that I’ll get good on the drums,
so I can become a big star.

The next day I’ll learn how to sing and to rap,
and practice some dancing techniques.
And, that way, I’m sure to be famous and rich
in no more than one or two weeks.

I just told my mother my excellent plan,
explaining the millions I’ll earn.
She told me that, firstly, I’ll need to learn patience.
So, how long will that take to learn?
