a large part of me thinks that
@Smont hit the nail on the head about removing distractions from life. I have three monitors open right now at work, I am replying to customers, working on a quote, entering orders, and thinking about this post. I sneak down to the gym for cardio at lunch and I use that time to watch educational videos on youtube about greenhouses, aquaponics, distillation, etc. I drive 2-3hrs a day commuting and I use that time to listen to podcasts, Hubberman, and many others. I get home and am usually doing 3 tasks at once. if my wife has a late night (tues/thurs late gym classes) then I'm usually cleaning, working the dogs, cooking, and if I can fit it in, running back and forth to laundry in between stirring vegetables, feeding fish, throwing a ball for the dogs, etc.
like we as humans don't know how to sit still anymore. we have become so insanely effecient at multitasking (even though some people don't believe its possible, I disagree) and cramming so much more work into every minute of the day, its no wonder our brains are so fuked and can't figure out how to sleep. those are 8 hours we could be doing 27 different tasks! ha
