5 years

I have been meditating twice daily since March 09th, 2012. Today, I complete 5 years of this activity. 

I have also been exercising twice daily for 15 minutes since the above date. These are free hand exercises and a type of pranayam.

By the grace of God, I never missed the meditation or the exercise even once.

So at least an hour daily. Lets do the Math. 5 (years) x 365 (1 hour everyday) = 1825 hours. I am closer to the 10,000 hour target.
