Probably indicative of some ego problem or other, but I can't stand being guided in meditation. I've had periods where I simply couldn't get away from intrusive stress (healthcare proxy for terminally ill parent), but if left up to my own devices, apparently my mind is empty of concern quite a lot.
When I ride the bike I'm literally unable to concentrate on anything, really, other than staying upright and how my body is responding. It's very nice. Skiing is probably like that for you?
