Hi Dan,
Congratulations on making the decision to learn to fly! You will not regret it. I also wished I had done it earlier than the age of 54, so you are ahead of me.
I would agree with what the others have said, ie a lesson a week if possible, and ask your instructor what the next lesson will be so you can read it up in the books beforehand and have a better idea of what you are doing (and why) when you come to each lesson.
Learning is fun, so just take it one step at a time, and don't expect to remember everything first time - you won't!
Enjoy your learning, and keep us all posted with your progress.
Cheers and good luck,
Neil
