My favourite poem
THE ROAD NOT TAKEN by R. Frost
  Two roads diverged in a yellow wood,
  And sorry I could not travel   both
  And be one traveler, long I stood
  And looked down one as far as I   could
  To where it bent in the undergrowth;
  Then took the other, as just as fair,
  And having perhaps the better   claim,
  Because it was grassy and wanted wear;
  Though as for that the   passing there
  Had worn them really about the same,
  And both that morning equally lay
  In leaves no step had trodden   black.
  Oh, I kept the first for another day!
  Yet knowing how way leads   on to way,
  I doubted if I should ever come back.
  I shall be telling this with a sigh
  Somewhere ages and ages   hence:
  Two roads diverged in a wood, and I--
  I took the one less   traveled by,
  And that has made all the difference.
