sometimes you just need a time-out ... you get stuck in a rut and it becomes less enjoyable. there have been days where i've been sick of skiing - and i love skiing more than just about anything else in the world. life is cyclical so don't fret! find a new climb you wouldn't normally do, go climbing with someone who inspires you or pushes you more than you normally push yourself, take some time off until you miss it, try a new sport for awhile ... lots and lots of options. mix it up, don't be so hard on yourself, and enjoy life!
