In reply to nikkihinton:
In the 20 years I've climbed, I've regularly had breaks varying from 6months to 18months from climbing. I've never had the slightest issue getting back into it.
At most, six weeks of decent training has generally got me back to within half a grade or a grade of my best climbing. That's been the case again over the last few months.
However, I've never been unmotivated as far as climbing goes and struggle a bit to understand how someone could be. But I do come into climbing from a very traditional hillwalking/scrambling background so whilst I've always climbed loads indoors and participate in trad, sport, bouldering, winter, big wall and alpine climbing I have never been overly preoccupied with grades. Climbing for me has always been associated with enjoying the outdoors rather than being just a performance orientated sport.
There are a lifetime of fantastic VDiffs and Severes etc. out there so I've always had the attitude that pretty much regardless of how fit/unfit I am or easy/hard I can climb there is still no shortage of inspirational stuff out there. One of my best days out last year was doing Tower Ridge for the first time in Summer.
I don't know what your background is or how you got into climbing but surely the whole point about climbing is that it is an inspiring, uplifting activity that is intrinsically enjoyable with grades and performance being of secondary importance.
