Who is it that says most? Which can say more (Sonnet 84)

Who is it that says most? Which can say more
Than this rich praise, that you alone are you?
In whose confine immured is the store
Which should example where your equal grew
Lean penury within that pen doth dwell
That to his subject lends not some small glory;
But he that writes of you, if he can tell
That you are you, so dignified his story,
Let him but copy what in you is writ,
Not making worse what nature made so clear
And such a counterpart shall fame his wit,
Making his style admired every where.
    You to your beauteous blessings add a curse,
    Being fond on praise, which makes your praises worse.
