Derek Medina - The man who wrote "How to Save Your Marriage" in the U.S.? He shot his wife... and posted the photo on Facebook. 

Dale Carnegie— the legend behind "How to Win Friends and Influence People"? He died completely alone. 

Benjamin Spock, who sold millions of books on parenting? His own sons tried to put him in a nursing home. 

Maria Montessori, the world-famous teacher? She gave her own son away to foster care, so she could dedicate herself to other people's children. 

Rhee Kun-hoo - Korean author who wrote the bestseller "How to Be Happy"? She hanged herself, after years of depression. 

What does this tell us? That the people writing self-help manuals... often couldn't save themselves. Coaches. Gurus. Trainers. Influencers. 

 They sell answers to life. 

They were just as lost as everyone else. 

Maybe even more.
