The 4 day week is something I aspire to achieve. Working 4 longer days to have Friday off sounds ideal, but clients just wont accept it - they want you working 5/6 days a week 10 hrs/day, and materials will always still be delivered on the day you aren't there!
Would take a huge shift to change the attitude, but personally I speak for myself when I say I'm over the super long days and 7 day weeks. Sure sometimes it has to happen - but the last 3 years I've got the impression that its become the norm for many of us to be working flat out while our clients are off on holiday or pushing you to get something finished so they can enjoy it for summer. It doesn't even calm down in winter anymore.
I'm not working myself into an early grave, there has to be a way to have some balance as a small business owner. Has anyone actually achieved this?!
