You are completely correct. I hate this stuff that's peddled on YouTube, it's pretty simple, ask yourself what do they get out of telling you this if they are making so much money doing it. They are making money selling you courses.
What made me more susceptible I think is that my father made his money grinding up, buying a few flats , moving into full on property development. I paid no attention to his business until it was too late for me to learn from him (he died). Sure I worked on his building sites as a teenager, grafted cleaning out flats after tenants moved out (this is while my mates enjoyed their school holidays). He did pretty well and I grew up in a pretty affluent way. The stress was awful for him. I believe it fucked him up a bit. I have a few bad memories of him being a bit horrible. I forgive him that now looking back at the pressure he was under.
After his death I was desperate to emulate him. I began to think working for a salary was a mugs game. I paid for some bullshit property courses. Never went all in on anything thank god.
Anyway, eight years later I've accepted what I am, I'm in a job I actually like. I'll plough my furrow doing software and getting better at it. It's modest, but it's more certain. And uncertainty is the root of stress for me.
One bit of advice he gave me when I was complaining about working and having a manager etc "son, the bank manager is my boss, he can call in my loans any time" I can see now that this is a great antidote to the bullshit financial freedom advice on YouTube
