You don't have to like them, but taking the advice of billionaires regardless if they're white or not is never a bad idea. Take what they say and adjust it to your lifestyle being a black man. Disregarding their advice because they aren't black is stupid at best.
I feel what you're saying, but there are certain factors that make their success different than a black man trying to make it.
One) They have white privilege and can move in certain circles black people have no access to and are shut out of
Two) They have access to resources that black people do not
Three) They have connections, nepotism, and can actually make short cuts without making sacrifices.
I learned alot on my journey to my latest job...the one thing that stuck out was...being a black man in America...you are alone. Period. No one will help you.
We don't have an "invisible knapsack" of resources to take from and use to further our lives.
Alright, straight up and down I was fukking homeless for a while breh. HOMELESS. If I was white? You best believe I could of found somebody to take me in for a while so I wouldn't have to sleep in my car. You best believe I could of had somebody give me a chance to make money, and hell, maybe even offer me some work and maybe get a human interest story out of it. Which would lead to money coming my way.
But nah, rather than complain, I just used fast food restaurant internet for a while to send out job applications/resumes/update my blogs/send important e-mails, made good relationships with people that worked there so I wouldn't get kicked out for loitering, went without showers for a while, took showers at gyms using free passes I registered for online, went without eating for a while, basically making sacrifices.
3 months later? I was in a boardroom on Wall Street.
So there, as a black person, that did everything possible...from making the best out of my college education, getting internships, graduating with a 3.9GPA, and having a degree...I still managed to end up in poverty and on the streets...but then again, I managed to work my way out of that situation to something better...
WHY? CAUSE I HAD NO CHOICE!
Becoming rich and successful is not an option...it's cause YOU HAVE NO OTHER OPTION FOR SURVIVAL.
That's reality for the average black person without connections.
That why I'd rather hear the advice from black people who made it, cause we all know we have ten times more obstacles in our paths...and those who did can honestly be seen as the best of the best, cause they made it even though the odds were against them.
No offense, but these dudes in the videos in the OP had 95% of their success laid out for them.
