I've just checked in at The Climbing Centre in Glasgow for my Intro to Rock Climbing Part 1.
I'm with nobody I know, I'm alone just now. I'm in a strange place that I've never been before, waiting for an instructor I've never met before, to do an activity I haven't participated in for over 25 years.
It would be fair to say I've had the "I'm not going in" or "I can't do this", but there is more to it than that. I want to do it. It's something I have thought about for years, and only just getting round to it now. I still have doubts "I won't be any good at this" but I have rationalised it with "I'm just starting, it's alright to be a beginner"
So anxiety turns to excitement, not all of it but some of it!!!
Take a chance, it might turn out to be fun!!! And if it doesn't you can recover.
