Hmm... here's a few lessons learned:
Don't be intimidated or discouraged if the CFI seems to be throwing a lot of info. at you- that's typical, and if the CFI is good, he or she will also make sure you are learning what you need to know to get started and have fun. They aren't out to spoil your fun- they just want to see how well you soak this stuff up, esp. if you have told them you're serious about learning to fly. You'll be allowed to forget some of it later, but not for long...
Be sure to acknowledge what you're being told (like if they say: "my airplane". Instructors like to know you intend to let go when they ask you to), and by all means speak up if it is unclear or you have some question about something the CFI hasn't mentioned. Feel free to criticise, also- you're paying for this. Their response may teach you something important (like that you don't know what you're talking about, or perhaps that this is somebody you won't be happy flying with), or you may remind them that they're still learning, too. Just save your critique for the de-brief , and think before you speak. My CFI for my 2-year review surprised me recently by asking me "How did I do?"- the mark of a good instructor!
It's easy to sort of fall into a trance the first time you grab yourself a handful of airplane- savor that moment, but remember, it's a flight lesson, and you should make the most of it. Daydreaming or fooling around is for when you're on the ground- real flight is like walking the razor edge between total abandon and the most intense, serious concentration... I love that edge, and I think you might feel at home there, too.
And if you're disappointed afterwards, feeling you could've done better, get over it- just turn that around and decide to fix whatever's wrong next time. And if the instructor rubs you the wrong way (liike if they yell at you or whatever), don't be shy about choosing a different one for your next lesson. Don't mean to be negative- it happens...and the instructor-student relationship must be harmonious, or your training will suffer.
As for the differences: no matter how good the FS model, it's not quite the same, handling-wise... and it's also very different when it's a dual lesson. But I bet you'll find that in many ways, flying a real 152 is easier than in the sim, depending on weather conditions that day.
Good luck, and let us know how much fun you had!!
