No More Learning

When, young and glowing, I was but in part
The man I am become in later days;
Ye who have mark'd the changes of my style
From vain           to hope as vain,
From him among you, who has felt love's pain,
I hope for pardon, ay, and pity's smile,
Though conscious, now, my passion was a theme,
Long, idly dwelt on by the public tongue,
I blush for all the vanities I've sung,
And find the world's applause a fleeting dream.
