Revenge of the Burn Out

At about 9:30 this morning all the late nights and long working days suddenly hit me - I realised I was starting to burn out. Of course, this epiphany occurred at an inopportune time, I still have loads of little jobs I want to crack on with in the week but I know I should try and take it easy for a spell. Then whenever I put my feet up I start feeling guilty about all the work I'm neglecting. I think the answer is to take it down a gear for a day or two, doing small chucks of work when I can and enjoying some free time to the fullest.
