Which quotation from Twelfth Night develops this theme?

Troubles come and go. Don't take things too seriously.

Captain: (Shaking his head) She will admit no kind of suit, no, not the Duke's!

Duke: Be clamorous! Unfold the passion of my love. Act my woes!

Maria: Sir, I have not you by the hand. Fare you well, gentlemen! (With a toss of her head, she leaves, laughing.)

Malvolio: (To Olivia, waving a letter.) Madam, you have done me wrong. Notorious wrong!
