I mean, these asvice "work really hard" sounds like bs to me. As a lot of people who fails don't work hard. As luck isn't necessary and people who work hard enough inevitably get lucky. I work hard and smart as I can. But I still know the odds are against me. Stories about how all my toughest troubles were solved by a legendary VC trusting me isn't much you can learn from.
If you're the type of person who say, "I will just quit" you might not be the type of person that a VC wants to fund.
I've heard it said (might have been from a Stanford ETL talk) that you should do a startup because when you wake up in the morning you absolutely can't do anything else. If I was a VC I would want to fund people with that level passion.
Access to capital or a VC is just a roadblock. Detour around it or take another road.
I agree with the general point, though - you need a certain amount of baseline opportunity to be able to do this stuff. That is a problem that needs fixing.
