What comes to mind today as I work to define the TenSmith 10 is several 90-10 references...
There is the 90-10 Principle "life is 10% what happens to me, and 90% how I react to it." It's one of life great lessons on attitude and how we control outcomes by choice.
There is Jack Nicklaus' quote about the game of golf being 90% mental, 10% physical.
The commonality in all of these, including the TenSmith 10, is that one small piece is key to the entire picture. Without the 10, the 90 means little.
Make your 10 count!
