When you get into a tight place, and everything goes against you till it seems as if you could n't hold on a minute longer, never give up then, for that 's just the place and time that the tide 'll turn.

Old Town Folks (1869) Ch. 39 (p. 507) Sometimes paraphrased: "When you get into a tight place and everything goes against you, till it seems as though you could not hang on a minute longer, never give up then, for that is just the place and time that the tide will turn." and "Never give up, for that is just the place and time that the tide will turn".
