I took a (quasi) sabbatical recently. I worked 1.5 days a week for one year. I dialed down my expenses so it was enough to pay the bills. It gave me the opportunity to work on some hobby projects, spend more time with my family and just enjoy life. It was fantastic. Now I am planning to repeat this every 5 years at least. I only wish my overworked friends did the same so I could spend more time with them as well.
