First things first: the following is not in any way intended to demean/attack/"throw shade" at you or anyone else in the slightest. Not whatsoever! So please forgive me if it comes across in that way despite my best attempts to the contrary.

The above, while fantastic for the person who lived that way, "smells" (for lack of a better word) like it comes from someone who hasn't been forced into a rough life. Bouncing around like that is easy when you don't have to worry about whether or not you'll be homeless in the next week because you were illegally fired from your job and the government doesn't care because it's not an easy open-and-shut case where they can automate litigation six years from now (because their caseload is literally that high).
You can't really do that kind of stuff when you have one - or both - parents dying from cancer and they both need full time, in-home care that, being unemployed, you can't afford to provide them. Especially when for whatever reason, they have no retirement savings, pension, 401k, absolutely nothing, and no health insurance either.
So please understand that while I'm honestly happy you've been able to do that, a lot of people just flat aren't for many reasons, the above being mere examples. You might think they're made-up, fictional or convoluted, but they're not: they're my life experience from 2017-2021. I lived those things, and worse, all at the same time.
> A brief note for context: you mentioned "pounds" so I'm assuming you're in the UK, which has a famously fantastic healthcare system. I'm in the US, where ours is...well, we all know what shit smells like, don't we? And herein lies a real life example of how government investment in people - aka "socialism" to some degree - is not a threat to an economy or capital investment, but in fact enables economic growth. /rant
Point is, for some people, that grind is the only thing keeping us alive. There is no safety net. There is no plan b. You either go nose-to-the-grindstone, or you go live under a bridge and eat scraps out out of the dumpster. There's no in between for some of us.
Again, not in any way intended to "throw shade" at you whatsoever. I'm just raising awareness that for some people, this advice, while technically valid and something I really wish was actionable for everyone, is in many cases just flat out impossible. You try it, you wind up homeless, a pariah, and unable to re-enter the industry because who's going to hire somebody without any relevant work experience in the last 3 years? Next!
