I think the point being made is that "love of flying" is what see's many (including myself) take to the air for less than decent money. If money is what you like then look elsewhere but more importantly - if "love of flying" is the overriding emotion then fly for fun and save yourself lots of hassle and disappointments. I only fly because I love it - not for money - this love will be abused by those seeking to make money unless you tread very carefully. Luckily, I have not allowed myself to fall into that trap due to my ambition and sights being lower... maybe that is the pitfall many fall into thus only ever becoming disappointed when they discover the harsh realities of pilot life?
VFE.
