Sonnet 150. O from what power hast thou this powerful might

O from what power hast thou this powerful might

With insufficiency my heart to sway

To make me give the lie to my true sight

And swear that brightness doth not grace the day?

Whence hast thou this becoming of things ill

That in the very refuse of thy deeds

There is such strength and warrantise of skill

That in my mind thy worst all best exceeds?
