Finish every day and be done with it. You have done what
  you could. Some blunders and absurdities no doubt have 
 crept in; forget them as soon as you can. Tomorrow is a
  new day; begin it well and serenely and with too high a
  spirit to be cumbered with your old nonsense. This day
  is all that is good and fair. It is too dear, with its hopes
  and invitations, to waste a moment on yesterdays.
 Ralph Waldo Emerson
  
 Never lose an opportunity of seeing anything that is beautiful; for 
 beauty is God's handwriting -- a wayside sacrament. Welcome it 
 in every fair face, in every fair sky, in every fair flower,
  and thank God for it as a cup of blessing. 
 Ralph Waldo Emerson
