Yes, it's a never-ending cycle if we arrange work around time schedules.
I'm not sure I have tips, but I wrote an article on what comes first, productivity, or reducing the amount of time spent working. People usually think that we have to be more productive first and get the reduced week time as a gift, but the Nordic countries demonstrated that it be the other way around.
Here's the article if you want to read it:https://medium.com/build-something-cool/increase-productivity-or-reduce-working-time-which-comes-first-bd575a96cdde
It's a very interesting subject: time, freelancing, productivity. It can make you think for hours.
Cheers!
