I could not prove the Years had feet

I could not prove the Years had feet—
Yet confident they run
Am I, from symptoms that are past
And Series that are done—

I find my feet have further Goals—
I smile upon the Aims
That felt so ample—Yesterday—
Today's—have vaster claims—

I do not doubt the self I was
Was competent to me—
But something awkward in the fit—
Proves that—outgrown—I see—
