The longest day has an end.

最难过的日子也会有尽头。

No, no, no, I can't see the end of such days, of course, if I choose to commit suicide, then all the miserable things will be brought to an end.

We can't help everyone, but everyone can help someone.

我们不能帮到所有人，但每个人都能帮到别人。

Care about your craft, think about your work.

Be an useful craftsman.
