"...given sufficient motivation"
I think that's the point, I've just looked at my log book, and during the seasons that i lived and worked in scotland, i only have about 10 days per season!!!
It's the same with living in north wales and being really picky about what weather is good climbing weather. If i'd just driven up from london, i'd make sure i got out climbing anyway, so that i hadn't wasted a trip.
So i think being motivated to get in amongst it is really important - cheers
