to strive, to seek and to yield sometime?

A disillusioned king, a wanderer, a hero who's purpose is served, a seeker who doesn't know how to die.

And Tennyson from 1833 coping with the end of a friendship.

I cannot rest from travel; I will drink
Life to the lees. All times I have enjoy'd
Greatly, have suffer'd greatly, both with those
That loved me, and alone; on shore, and when
Thro' scudding drifts the rainy Hyades
Vext the dim sea. I am become a name;
For always roaming with a hungry heart

I am a part of all that I have met;
Yet all experience is an arch wherethro'
Gleams that untravell'd world whose margin fades
For ever and for ever when I move.
How dull it is to pause, to make an end,
To rust unburnish'd, not to shine in use!
