Tear our pleasures with rough strife / through the iron gates of life

If SC can quote Marvell, so can I. Mine is only a fragment:

...Now therefore, while the youthful hue
Sits on thy skin like morning dew,
And while thy willing soul transpires
At every pore with instant fires,
Now let us sport us while we may;
And now, like am'rous birds of prey,
Rather at once our time devour,
Than languish in his slow-chapp'd power.
Let us roll all our strength, and all
Our sweetness, up into one ball;
And tear our pleasures with rough strife
Thorough the iron gates of life
Thus, though we cannot make our sun
Stand still, yet we will make him run.
