Backpacker has hit the nail on the head,
You sound like i did when i started but dont worry, like backpacker was saying, the cold crisp morning are very good with little wind and also book a few hours in a day.
When I started I did some general handling and then did circuits all the time, but trust me it is worth it, when u have done enough and the instructor feels you are ready then u can go solo for your first time on the circuits, then you will move on to other things.
How many hours you done?
