It breaks my heart to see smart, capable, driven individuals working intensely hard but not paying attention to their health.

Because I too was once one of them.
Until I decided to make 3 changes 

  1. Health – working out every day, for 1.5 hours – tennis and strength training 
  2. Diet – eating healthy, home-cooked, with my last meal before sunset
  3. Mind – meditating every day for 30 minutes

You can have it all, but if you don’t have your health, you really have none of it all.
