how long do you think it will be before a 15 hour/year pilot renting the typical piece of flying scrap metal is going to say to himself (literally or subconsciously) : "this hobby is such a huge hassle, it costs me so much money to do the 15hrs, I get so little in return for it, I have such poor currency that I can't go anywhere, nobody but absolute anoraks wants to fly with me in the piece of crap that I can get, a lot of people politely refuse to fly with me because they are horrified at going up with a 15hr pilot (**), there is close to zero crumpet hanging around this scene AND/OR my wife/gf can't see the point of me doing this since I never take her anywhere nice... I might just chuck it in and put the £1500 towards an upmarket gym membership and an upmarket tennis club membership (both of which will provide much better scenery)"
Hmmmm.... The people I know who fly that amount say (literally or subconsciously), something like this: "This hobby costs me more than I can afford, and I wish I could be more current and fly to some places further away. But I just love getting airborne! I fly a C152 because it's cheap and forgiving and what I can hire, and I spend all week at my boring job just looking forward to being able to fly at the weekend, even if I only do half an hour of circuits. My friends aren't that interested in flying with me, and my wife thinks I'm crazy, but it gives her a chance to go shopping alone, and I have the company of my fellow aviation addicts at the club. I suppose I really ought to chuck it in, take my wife nice places, and get a gym membership to keep fit. But my wife seems happy the way things are, and I hate the gym and I'd never fit in with the toffee-nosed snobs at my local one. And for me, nothing, but nothing, beats the sheer joy of slipping the surly bonds of earth and being on my own up there in the wide blue yonder where nothing and nobody can touch me. I've felt that way all my life and I think I always will".
Everyone is different. You don't have to agree with someone's point of view to understand and respect it. Does yet another thread have to turn into "there are those who do my sort of flying, and the stupid ignorant fools who'll probably give up anyway".
