“Let me tell you the secret that has led me to my goal. My strength lies solely in my tenacity.” Louis Pasteur (1822 – 1895)
Tenacity has  worked so well for me through the years.  A personal example, I first broke 100, 90, 80 in golf by my old club putting two 9 hole plays together.  I said, “Wow, keeping my concentration, focus the whole round of 18 I can shoot ……  I CAN do this.”  I found this as an incentive finding what would help me do this.

Do you need help with concentration, alertness, tenacity?  Allow me to assist you.
