Great article!  I fully agree routines in life are the keys to success.   

I'm in my late 50's and have a busy successful career in finance.  I believe the key to my success in business and life, is getting up early (before 6 am) and exercising 6 days a week.  Heavy compound exercises 2/3 times a week and on my off lifting days I'm doing cardio.  I only see 20-year-olds in the gym at that time of the morning.  I feel great, I have lots of energy, I have a positive attitude and I have a side benefit of looking a decade younger than my peer group.

The secret to success is the discipline to follow a routine for decades.
