Corporate wank culture makes you forget that the boss of every company does whatever he wants, is petulant and throws tantrums, thinks he is always right and justifies it by saying everyone who works for him is a lazy loser who doesn't have any balls.
I don't know if other ADHD sufferers have this experience, but it feels like every bit of work I've ever done turns to nothing.
I have loads of experience doing loads of things, but it honestly feels like every project ends up in wasted time and something not working.
