Does no-one just fly with a map and a stopwatch any more ?
I haven't used them in years. I usually leave the GPS at home as well, I use the view out the window for navigation!
More on the topic, fly because you enjoy it. That's not to say that you should not fly if you're not enjoying it, but hopefully the lack of enjoyment is either very brief, or replaced by pay! If you're not enjoying being with your instructor, discuss it first, then change instructors if it's not improving. Don't rush toward the goal of a PPL, but rather enjoy your way along as you learn.
