I recommend also reading "The Most Misread Poem in America":

  Most readers consider “The Road Not Taken” to be a paean to triumphant
  self-assertion (“I took the one less traveled by”), but the literal meaning
  of the poem’s own lines seems completely at odds with this interpretation.
  The poem’s speaker … has already admitted that the two paths “equally lay /
  In leaves” and “the passing there / Had worn them really about the same.” So
  the road he will later call less traveled is actually the road equally traveled.
  The two roads are interchangeable.
