Warren Buffett 
"Our stay-put behavior reflects our view that the stock market serves as a relocation center at which money is moved from the active to the patient."
"We continue to make more money when snoring than when active."
"The only value of stock forecasters is to make fortune-tellers look good."
"My favorite time frame is forever."
Peter Lynch "Far more money has been lost by investors preparing for corrections, or trying to anticipate corrections, than has been lost in corrections themselves."
"I can't recall ever once having seen the name of a market timer on Forbes' annual list of the richest people in the world. If it were truly possible to predict corrections, you'd think somebody would have made billions by doing it."
