If you do not, your parents for sure will remember Wayne Dyer, and most probably they have read or at least heard from his first book, Your Erroneous Zones (1976), one of the best-selling books of all time, with an estimated 100 million copies sold to date.

Although knowing that Dyer's nickname being the “father of motivation could immediately scare you back, and understanding that you are more than fed up with this positivism tendency of being the best version of yourself, I highly encourage you to read, and remember these 10 Pieces of Wisdom assigned to him. 
 
On my humble opinion, they are not about looking at the bright side of life, they are about learning how to see, learning how to think.
