I'd rather prefer a 4 day work week.. I get in and out of the zone completely so to get out and in just for 2 days is a lot of work.. My ideal week will look like this **2 high productivity days - 1 learning/low productivity day - 2 high productivity days** then zone out for 2 days.
yes, this is such an amazing way to encourage R&R and spur productivity in the process. It 100% fends off the end of the week lag. Well rested people are more productive. Now that I freelance FT, I always make Wednesday a half day - I enjoy the sun, have a long lunch, and rest so I can get back into it for the rest of the week. I tend to be way more productive on Thursdays and Fridays when I recharge on Wednesdays.
