Don't worry, chill and enjoy. Gliding isn't a race to get little stickers. It took me 9 years to get my silver C. Not because I'm crap, I just couldn't be bothered. I was happy staying within range of the airfield (which of course can be some considerable distance depending on glider type/weather.) I spent 9 years just getting that 'It's just good to be up here for a couple of hours' out of my system. When I decided I wanted to go further afield I did my silver. Simple as that.
