The Top Four Enemies Of Businesspeople

In his book Get Smarter,
billionaire Seymour Schulich talks about
the top four enemies of business people,
Ego, Greed, Alchohol and Drugs, and
Assistants With Big Breasts. 

Of the four, Ego ranks as number one. 
“This one destroys more people
than any other single thing.” 

How do I keep the ego in check? 
By trying new ventures or assignments. 
Nothing makes me as humble as
going into a placement knowing
I don’t know what I’m doing.
