I'm a big advocate for doing less in order to enjoy life more.
One thing I really enjoy is a pure unadulterated PJ day.
I encourage you to dedicate a whole day to staying in your pajamas all day. I'm talking 9-5, wall to wall slobbing and snuggling up on the sofa.
You can do it on your own or with your family but you all need to agree to stay in your PJs all day.
Watch a box set, have a movie marathon, binge on your favorite comfort food, light some candles, take a nap and turn off your phone.
If you really can't take a full day off, try and save up all your jobs and commitments for the afternoon so you can at least have a PJ morning before you have to get up and be a grown up.
All duvet days should be planned for when you are not supposed to be working. Please do this at the weekend or on a pre-arranged day off!
