Different people need to earn different amounts of money to fund their different lifestyles.
If I didn't work similar hours to what you said I wouldn't have any of the nice things I have.
I've had a month off between jobs and I've just turned into a lazy b*****d and it's boring.
Would love to go travelling but for this I will need some thousands of pounds, which isn't just going to appear is it, and working part time so I can live life to the fullest isn't a viable solution.
So basically your entire philosphy is to earn/work the bare minimum you can afford so you can live in the moment (read: hand to mouth). Imagine if you worked 8-12 hours a day, earnt decent money so you could do something amazing in the long term instead... That or obviously get a job with short hours and MEGA pay - if it was that easy, everyone would do that.
P.S - I haven't watched, and have no plans to watch the videos you've posted.
If it's any consolation I used to have the same attitude when I was about your age, until realised what a f**khead stoner way of thinking it was.
