Joseph Brodsky said this quote

“ Try to embrace, or let yourself be embraced by, boredom and anguish, which anyhow are larger than you. No doubt you'll find that bosom smothering, yet try to endure it as long as you can, and then some more. Above all, don't think you've goofed somewhere along the line, don't try to retrace your steps to correct the error. No, as the poet said, Believe your pain. This awful bear is no mistake. Nothing that disturbs you is. Remember all along that there is no embrace in this world that won't finally unclasp. ”
