Not a single wasted word in this poem. About a person (me) assessing their life at the midway point … and approving of the report. 

As I tread this life’s midstream, 
Something blue occurred to me: 
All my lavish boyhood dreams, 
    Hath faded to perfunctory. 
And though a strict retrospect, 
May deem my days part misspent, 
Awash, I’m not, in regret; 
For when I think of how I’ve lived, — 
Lo, the less I’ve sank, 
    And the more I’ve swimmed!
