I’ve personally done this and have started long-boarding, playing indoor soccer and going to the gym four days a week. I’ve been doing this for about 2 months now and funnily enough, I now have more time as my productivity has gone through the roof.
The new schedule has forced me to become more organised and the exercise has allowed me to stay up longer. I’m no expert in organisation or productivity, but I’ve certainly noticed these areas improve over the past two months. I wish I had done this earlier.
I’ve also started reading more and am currently getting into ‘4 Hour Body‘ by Tim Ferris and ‘Yes! Attitude‘ by Jeffrey Gitomer. Both great books. Inside 4 Hour Body, Ferris asks Richard Branson “What is your number one tip for productivity?”. Branson’s reply: “Work out”.
