Forever, for Always, for Certain Lyrics

Forever ain't easy to come by
For always ain't never to sure
For certain is less than you hoped for
For someone it's hard to endure
Foresaken must sometimes befall us
For sorrow sometimes will call
Four seasons go around on a pinwheel
And tomorrow ain't nothin' at all
[ Lyrics from: http://www.cloverlyrics.com/e54048-guy_clark~forever_for_always_for_certain_lyrics.html ]
The first time that I came by lovin'
Forever was all on my mind
And I never got used to the hurting
Or the searchin' for some love in kind
And it seems like I'm still chasing rainbows
It seems like I'm still on the run
Forever don't mean much in passing
Forgotten don't mean that it's done

Forever, for always, for certain'
For someone forsaken for sure
For any old plan you got workin'
For any old pain you can cure
Forever, for always, for certain
