I, too, have read pprune stories of people taking off and landing after 2 hours or so (funnily enough, never met anybody at the club that has done it !)
I started flying less than 7 months ago with a 5 hour package, and by the time I got to the 3rd hour, I thought I had wasted my money - thought I wouldn't even fly the remaining 2.
This is not for me - What a waste of money - I'll never make it and so on.
As a matter of fact, each lesson became less of a struggle and now I am at 40 hours (10 of which solo) preparing for the skills test.
Difficulties make success much more enjoyable. I would sincerely give it a little more time before you call it a day.
