"Don't go into programming, you're not in Silicon Valley and life isn't like what you see on the internet, you have a good thing with your grandpa, just become a Mechanic like him"
My biggest passion in life have always been with computers, and I know (Now even with empirical experience) that I'm a horrible fit for a mechanic
But lets say I wasn't, and take it that it wasn't said in bad faith; It still enraged me that he didn't thought I'd be capable, I managed to learn and earn enough, escape my birthplace and (Sadly) The good thing my grandpa had going on went down in flames (Due to external circumstances)
It's been years and it still pisses me off, but I'm confident that he doesn't even remember that we ever talked about it
