Richard Branson, the English entrepreneur was asked what is the single best think to do to increase productivity. His answer was very short: “Work out.”
The inside is different than outside quip is just not true at all. If everything is working inside your body how it’s supposed to, if you are insanely fit and healthy, than the outside is going to be the same. Productivity included. You will be insanely productive.
The opposite is true too. If your inside is broken, if you don’t feel good, your health is not that great, than the outside is going to be the same. Productivity included. You will not have the energy, enthusiasm and drive to make things happen.
I met Sir Richard Branson on the airport few years back. He is insanely fit. His productivity is insanely high. His inside reflects the outside.
Stop looking any further. This is it. Wanna improve your productivity? Work out!
