Hahaha - with 3 hours in the saddle I think you're doing just fine!
In my first lesson I did as I was told and thought 'wowww... this is amazing!!'. In my second lesson I didn't and promptly fell off

. I'm STILL learning the lingo! It was only 5 minutes before my first competition that I worked out how to bridge the reins on a snaffle-bitted horse. I have no idea about riding one handed with split reins - but a friend gave me an interesting demo on Saturday of how to shorten reins with one hand with a camera strap!
One year on, I can just about keep my heels down, bump with one or other leg as needed and am getting the gist of framing up and releasing - but only just... I occasionally beat myself up for being completely incompetent and useless, and recall just how whizzo I was as an English rider

BUT... then I remember that I've not been so totally interested in any other riding method since I was about 10, and realise that I'm willing to spend most of my spare time learning more and more. In the meantime, I've had a ball and have got to compete already and meet some hugely talented and helpful people even as a TOTAL NOVICE. Can't get better than that, surely??
