No, the biggest thing holding people back from doing great work is resources. Everything else is a distant concern.
Remember what Y Combinator does? It connects people with resources, to people who claim they'll do great work.
Good, boring, mundane redistribution of resources from old rich people to young capable people. Good, do more of that and please spare us your 'wisdom' - it leads to bullshit artists whose sole skill is 'appreciating' your 'wisdom' to insert themselves into the process and ruin the whole thing.
