I've been mentally juggling the following for a few months. I've worked essentially 7 days and nights a week for the previous decade, but now find myself working 4 days a week - and frankly, loving it in comparison. (My son was over 18 months old before I spent greater than a continuous 30 minutes with him). Ongoing time catching up with family and self is important, but at a cost of working the 5th day with at least a possible 1/3-1/2 supplement in income. Is it worth it? For what proportionate increase would you work this 5th day? Or a 6th? A 7th? If you earnt 50, 100, 200, 300kpa? Does it change? Or is our free time priceless?
