How many times have I seen that field/house/building etc?
When will I actually earn a living out of this?
What if I did a demo of a spin right now?
How many trial lessons can you do in a day?
I know you've never flown before but is it really that hard?!!
and many other such thoughts - sad but true.
I love flying and I like instructing, I even really enjoy showing people the joys of flying in a light aircraft - I just get a little wistful in those quiet moments.
