Welcome to the best (if arguably!) the most expensive hobby in the world!
I wish i had kept a PPL diary now, but more than over half way through training its not really worth starting. As I always say, the instructor in my view is the key. Find a good 'un and you'll love your flying. You'll have days where you want to forget all about this idea of being a pilot, and other days when you feel like Top Gun! A good club is also beneficial...nothing better than stepping out of the aircraft to refuel and finding a row of friendly faces asking you how your flight went!
Above all, enjoy it, you obviously have oodles of enthusiasm and that, adn (hopefully) the faith which your instructor has in you will get you through any sticky patches and make you feel 10feet high in the (Many) good patches.
Good Luck!
