People consistently ask where my diligence comes from either at work and my work ethic or my speak of the gym or how seriously I take my nutrition (which is way more diligent than it used to be) .
My answer is I grew up a gymnast my first true love of being athletic and my coach instilled in me that diligence breeds success. I asked him how can I do this or that, a new skill or trick. His answer was always be diligent on the approach and the skill will become easy. Every night till college I did crunches and stretched before bed. Took about 30 min to run through my routine but it was worth it.
Now I work hard at work , at the gym , and at home. It's the only way I know how to live. And I am very happy with how my life has turned out.
