I didn't exactly get the "flying isn't for you" speech from an instructor, but I did get a concerned instructor worrying that I was wasting my time as I couldn't get the flare right ...
So I reassured him that this was precisely where I was expecting trouble, as it was hand-eye coordination and real-time calculus stuff that I wasn't very good at (I'd never been able to catch a ball as a kid), and I didn't think I was wasting my time and money, and we just carried on for another couple of hours until I got it.
