I recently reduced my weekly hours and am now working only 4 days a week. its so much better.
People are dumbfounded when i tell them, they do not understand that free time is more important to me than money. as long as i can live comfortably and use my new free time i will trade money for time. end goal is 2 days a week - no idea if thats possible, but 3 days is a must.
if you can do it financially and with your job situation i can only recommend it. i still giggle like a little girl every friday because i dont have to go to work
