I am really happy for your sister and the many other people who just push every day to get up, not feel sorry for themselves and make it work. Thank you for the encouraging words.
There's nothing strange or unusual about that.
I met a lot of people that were a lot smarter than most "startup developers" and it didn't require them to sit in front of a computer most of the day.
If someone is of average or higher natural ability, yes, hard work and perseverance will be the biggest determinant of outcome. But someone who's genuinely pretty dumb, wholly socially incompetent, or exceptionally disabled or ill will have massive difficulties being successful regardless of their perseverance.
Which isn't to say that hard work is useless to the people on the lower end of the spectrum: far from it, a stupid hard-worker not only can find themselves with a decent enough job but will usually be able to keep it. It's just they lack the ability to set themselves up for good opportunities like that and to limit downside risk from one-off events. Luck of the draw will end up dominating outcomes.
(Obviously, most people who comment on internet forums, particularly a specialized forum like HN, are not only likely to be average or above but also to have extremely limited contact with people significantly below the mean, so if you're reading this, your life outcomes probably are determined by your own work ethic. On that note, cheers to a productive Sunday!)
I agree. I consider some of the inmates I deal with day to day very smart when you want to understand their world, and they will be more successful than anyone else when the game is being played on their turf. Sadly, they have other "distractions".
But, she wanted to be a police officer, and that required college. So she put herself through school by being a prison guard. My little 5'3" sister running around bossing grown men like it was nothing.
She made it through school and got hired as a police officer. She spent the next five years as a dispatcher. Nobody wanted to put her on the streets. But she persevered and eventually she won the day and became a patrol officer. I dare say except for getting married it was the happiest day of her life.
Don't let anything stop you, man. Smart isn't everything: perseverance counts for a great deal.
