To paraphrase Groucho Marx; "I would never join a profession that would have me as a member!"
Seriously, I'm professionally employed in aviation, in a job which brings me into daily contact with pilots, involves flying (albeit the simulated kind) but have never had the urge to learn to fly. If a spotter is someone who enjoys looking at aircraft then I certainly qualify, an affliction which shows no sign of abating as I get older.
Besides, like
Heathrow Director , all my spare cash is spent on ham radio gear!
