aaannnd . . . . Whoosh!!
It isn't about how good you are; in fact it is the opposite.
My grandfather was an engineer and focused on building actual things - being a productive member of society. He was also pretty alert about avoiding addictive things.
His point was that the gifted minds — who can get and ARE very good at chess — tend to get addicted and squander years or decades just chasing the next tournament, the next 100 GM points, the next high, producing nothing useful, and getting no skills applicable to productive pursuits.
He did not want to see me go down a path that could lead to being a chess bum any more than he'd want to see me become a ski bum, join a cult or just become a hardcore partier. All are surely enjoyable, but not a productive addition to society.
(& no, I haven't got a shred of insecurity about my abilities; I was getting good at an extremely satisfying rate, but also saw what it would take to get really good, and that I'd be better off spending my time not memorizing every classic opening and variant, but instead on understanding physics and chemistry concepts ... I absolutely see the beauty of chess, and may well take it up again, but I also am grateful for by grandfather's point, especially considering how addicted I got to the adrenaline of ski racing at international levels...)
And if you enjoy it and have the freedom to do that - fantastic - it's your life, do what you want - I hope you get as good as you desire and enjoy it!
