Waiting has its own beauty. If you are waiting for the bus, you are reading HN on phone, or listening music or just observing. In today's world, where you are bombarded with stimulation, you will always have the impulse to do this or that or visit someplace or follow a fashion. Sometimes is just nice to wait or you won't be able to experience life fully.

Beautifully explained Elizabeth Jennings in Delay:

  The radiance of the star that leans on me
  Was shining years ago. The light that now
  Glitters up there my eyes may never see,
  And so the time lag teases me with how

  Love that loves now may not reach me until
  Its first desire is spent. The star's impulse
  Must wait for eyes to claim it beautiful
  And love arrived may find us somewhere else.
