It basically said that we're NOT physically "set up" to work 6, 8, 10 hours straight... that our days should consist of periods of alternating rest and work.
It all sounded a bit "hokey" until I tried it.
3 years later and I STILL work this way.
Think of your work day as consisting of several sprints instead of a marathon session.
So, for me, I start at 8 a.m. or so... work until 10:00 a.m., take an hour break, work from 11:00 a.m. until 1 p.m., hit the gym, and then work from 3 p.m. until 5 p.m., have dinner with the fam... and work from 7 p.m. til 8 p.m.
Anyone else work like this, staggered throughout the day, instead of straight shots?
I've noticed I have so much more energy/focus/concentration when I work in "bursts" or cycles instead of 6 hours straight through.
