I find it's best to have a desk.
Stick radio on. Not TV.
Go OUT for a walk / coffee at lunchtime.
You will oddly find you get more work done.
Lastly finish off the 5-5:30 bit by finishing off work by drinking a beer and wonder why you never did this before.
Simply ensure there is enough activity on your laptop to give the impression you are working.
Apart from that have a lovely day off and enjoy the sunshine.
