Great expanse, a sonnet

Earth, air, water, fire
Grant me this my one desire
My heart and will are strong
To last this expanse so long
I know that dreams prevail
While present self-belief grows frail
Yet day to day's a waking dream
Of hot, of cold, of see and seem
When I can't take another moment
Here's another thousand moments
Good things come to those who wait
But sometimes good things come too late
Will I last or quietly expire
Awaiting that one true desire
