Like most hands on self employed people, I tend to not take enough holiday time - and I sometimes suffer for it with lethargy, stress, and general physical aches.
I'm off for a week soon. Nothing fancy. Just a jaunt about 150 miles across to Somerset. I'm greatly looking forward to it. It will be good to chill out for a week. I've earned it. I never switch off totally though. Always have my landline on divert to my mobile in case any new enquiries come in.
