Ugh that subreddit is just a cesspool. Most of the stories are fake and it attracts the bottom feeders of society. People need work to feel fulfilled. I get that a corporate job may not meet that demand but this idea that you can just eschew any work and be mentally ok isn't true.
How is working a job that you know is completely mind-numbing and pointless to enrich some other person meaningful in any way?
Who is forcing you work a mind-numbing job?
Do you want everyone else to pay for you to do nothing? Do what you want, but don't expect others to donate what they've earned to your finger painting or whatever it is you think you should do to be fulfilled daily. This idea that everyone will just suddenly become creative happy geniuses as soon as "mind-numbing" work is alleviated is false.
