Today if you did that you'd be seen as "extreme". There's a growing trend among some in my generation where this is becoming common place. We're throwing off our generation's norms of spending shackles and approaching an escape velocity of leaving our friends behind. Some will eventually quit the rat race and retire very early. Others will continue and try to maximize their investments. They will become billionaires.
One thing will combine all of us though. They all will be financially successful to varying degrees. They will all accomplish incredible things in the eyes of society. Not just incredible, but some will say impossible. They will continue to say that it's impossible until enough do it. Break off the restraints of what society tells you! Break the rules! Save 70% of your income, not that measly pussy ass shit of 10%! Anybody can fucking do that! 10% is for sissies!
GET EXTREME! MAKE 70% OF YOUR TAKE-HOME-PAY YOUR BITCH!
