Well after all the encouraging responses on here I went into my second lesson today with enthusiasm and didn't worry when it took me a while to grasp some of the concepts, as I now know is normal.
I'm pleased to say I enjoyed it much more, was more confident controlling the aircraft and although I have a very long way to go I feel like I'm going to give it my best shot.
Actually looking forward to getting back out there next week now! Thanks again everyone
