Struggle Metaphors

[ohlhauc1]

Does anyone know some good metaphors pertaining to struggle?

I need to create a title for an essay and I think a metaphor is the best way to go. The essay is about how humanity is bounded to struggle forever. So far, I have:

Shackled to Struggle (which is not really a metaphor)
To Struggle Forever and Always

[Il Penseroso]

You could always think of Atlas, although he's a bit cliche.

[Redzeppelin]

I think the metaphor should relate to the actual "struggle" that your essay examines. What do you mean by "struggle"? The type of struggle will decide the type of metaphor that is most appropriate.
