Well done mate.
It's a strange mentality int it that drives you on to keep bashing away at something which is ultimately so unimportant yet at the same time so utterly absorbing.
I've had a couple of hours off work this afternoon and thought nothing of a 45 minute drive and a (beautiful) 30 minute walk to get to a crag to spend an hour or so totally focused on a 30ft section of rock never more than 3ft off the floor.
(You'd love it there by the way, incredible peace punctuated by the sound of wildfowl and other birdsong - brilliant place!)
