I have the other problem: not enough time.
Over the last couple of weeks I only spent a few days in the shop, and there always seems to be something else that needs doing: replace a fence, repair the fascia boards on my workshop, rearrange the guttering, fix a leak that meant I had 12ltr of water in the shop, find a fault in the electrics (mice eating cables, it turned out) and the list goes on and on. I just hope that eventually Mr Murphy will run out of things to throw at me.
