For until this moment he had lived in a state of pure possibility, not knowing what sort of man he was or what he must do, and supposing therefore that he must be all men and do everything. But after this morning’s incident his life took a turn in a particular direction. Thereafter he came to see that he was not destined to do everything but only one or two things. Lucky is the man who does not secretly believe that every possibility is open to him.
As Lawler summarizes,
Without some such closure — without knowing somehow that you’re “not destined to do everything but only one or two things” — you never get around to living.
It’s taken me a long time to understand that deliberately closing off some options can open more interesting options.
