There's been a lot of talk about a four day work week. Adam Grant, a Wharton professor and best selling author, recently tweeted "I've been working a 4-day week for 3 months now, I am much happier: my motivation to do my work is way higher as I know that I have more time to also use on my own projects..." Do you think you could get the same work done in 4 days as 5?
