I think this is good advice for a lot of people, maybe including the OP. Sadly, some people will never be prepared to "unplug from the Matrix". They wouldn't be able to handle the unlimited freedom and time without turning to vices. Especially if they've had their soul crushed by 20 years of a career and responsibilities, and they've forgotten all of their hobbies and interests. I'm not being sarcastic, I think this might actually be true for most people.
This advice doesn't really apply if you are any of the following: young, creative, already self-employed, an entrepreneur, or you don't care if people say that you're "not a man".
I've been freelancing for many years, so I feel like I already have one foot in the door. I'd much rather have a lot of free time to work on my own projects and hobbies, especially the ones that will never make any money. Even 5-10 hours per week on freelance work is really annoying (because of context switching), and I'd much rather be doing my own thing.
