Reality check on advice for statement of purpose I'm about to write a statement of purpose for graduate admission and my advisor passed along to me the following pieces of advice to keep in mind while writing  (based on his style and experience in admission commitees). 

I completely agree with every point he has made. However, I'd like to have further insight and suggestions and yet another reality check on the soundness of these pieces of advice. 


  Advice from my advisor:
  
  
  Don't try to sell me my own research area by explaining to me how fascinating it is. Do show your interest by showcasing your previous
  experience working on (or studying) related topics (not necessarily
  very closely related).
  Don't tell me how amazing, prestigious, perfect my institution or research group is. I know more than you do about that. Also, chances
  are that you are applying to a lot of schools and don't have
  inflexible interests yet, which is fine. Just tell me that you may be
  willing to work with a certain research group that seems more or less
  in line with your previous experience or future directions.
  Don't tell me a cute story about how you fell in love with my field when you were a kid (or high school senior or college freshmen). I
  just don't care. I want to hire a soon-to-be professional to join my
  research group, not a little boy with a cute story. I only need to
  know factual information that show your commitment to the field (for
  example, courses/conferences attended, projects undertaken).
  Ban ill-crafted, pseudo-literary, flowery, cheesy narrations. Just  write facts. Straightforwardly. Succintly. Accurately. I'll draw conclusions for myself.
  Ban any buzzwords, meaningless adjectives and adverbs. If they don't add concrete information, but are there just an ill-advised attempt
  to impress, cut them!
All good advice.  In addition, may I suggest that a statement of purpose should answer the question, what will you do if they admit you?  It should be 
future-oriented.  What are your goals and what are your plans for getting there?
