The Self-Aware Dilettante

A Jack of all trades,
but a master of None.
Soon he'll hope to learn something from them.
Sooner he'll fail
Pick up one,
Forget two.
Love another,
and lose it.
Is it so that to master one trade
is to neglect all others?

As most fade with age,
perhaps he'll learn to keep some.
It's best to be a Jack of all trades,
and a master of One.
