Jill of all trades, master of none

Michelangelo's Sistine Chapel.
Leonardo Da Vinci's Mona Lisa.
Homer's The Odyssey.
Syliva Plath's The Bell Jar.
Gustave Eiffel's Tower.
Michael Phelp's gold medals.
Coldplay's Viva La Vida.
Paul Simon's Graceland.
Walt Disney's... World.
Masterpieces.

I have this deep, embarrassing desire to leave this world with a masterpiece.  This desire, for once in my life, is not breed from pride, but from wanting to produce something spectacular.
I have so much in me that wants to come out.  This manifests itself in stacks of artwork in my closet, journals bursting at the seams, making up songs in the shower, and agonizingly sleepless nights laying as the wheels turn and turn and turn.
If I don't leave a masterpiece, then I, at least, want to have the skills and ability to do so.
I want to master something.
I am a Jill of all trades, but a master of none.
