Lead me, Master of the soaring vault
Of Heaven, lead me, Father, where you will.
I stand here prompt and eager to obey.
And ev’n suppose I were unwilling, still
I should attend you and know suffering,
Dishonourably and grumbling, when I might
Have done so and been good as well. For Fate
The willing leads, the unwilling drags along.

– Cicero (via Seneca)

Also quoted as:

Fate leads the willing, and drags along the reluctant.

– Cicero
