All of the pep talk type Youtube channels that OP mentions (Gary Vee, Mark Cuban etc), they push (IMO) a wrong idea of startups : they all say you should work 16 hours a day, bare minimum sleep, hustle and grind (god, those words make me cringe). That advice completely ignores health and general well being, which is essential if you're in it for the long haul. Anyway, this list seems interesting. Thanks OP for compil…
From most of the GaryVee content I watched recently the general feeling I took away is that many people are looking for the "quick fix" when really they just need to put in the hours. Not necessarily unhealthy hours, but hard hours never the less. And that they just need to do, and not think or plan in many cases. Try this one: https://www.youtube.com/watch?v=qRj144Gd7EA
Secondly, personally I found it really enlightening watching Casey Neistat's youtube VLOGs to see when he was very intentionally carving out time for family, and other things like running. You would see him intentionally rush home so that he could spend an hour with his baby daughter before she went to sleep - even if he had to go back out to work afterwards.
Of course, that's easier than it might be for some when you can ride a skateboard home from work in 10 minutes and a similar time to where his Wife works (he would carve out date time etc as well in the middle of the day). Never the less I thought it was good to see the very intentional time carving, especially from someone clearly so busy and juggling a lot of priorities (starting a company, a daily vlog, a new baby/family and a personal life).
Despite all of that, it certainly was having impact on his life but it seemed clear to me the impact would have been much worse for some people not taking that very intentional and active effort to carve out time for these things.
