"The thing always happens that you really believe in; and the belief in a thing makes it happen."
-Frank Lloyd Wright
I think everyone knows it's in their best interest to think positively, a nice little reminder can't hurt though.
I really believe that being hopeful & optimistic almost always leads to a positive outcome. John Cusack's character ( Lloyd I think?) in the movie "Say Anything", is often quoted as saying something along the lines of... "If you start out depressed, everything turns out a pleasant surprise." ummm maybe, BUT if you start out depressed you stay depressed! If you feel like your in a funk you need to get moving and think happy! Seriously, sad thoughts only bring more sad thoughts.
Of course these are only the opinions of lil ol Miss Fina, but I'd say I have a little bit of experience w/ the subject. :)
