I think the only original plan should have been get a real paying job to feed the YouTube and hobby stuff.
Accumulating enough wealth/savings in the process.
Then if there was enough safety net go full time.
That ship I'm sorry to say has sailed along with the youth and energy necessary to do it.
I myself was successful in running my own shop repairing everything.
As I got older I found I had nothing saved and no real insurance.
Then it happened, I blew out my back. Fortunately it was at a remote sub contracted job and all was paid.
It was then I decided at age 30 something to get a real job with paid vacation and benefits and leave the worrying to someone else.
After 20 years, I had accumulated enough to buy a house.
Not a fancy house, but one of my own with no one to hold anything over me (take it away) as I paid cash.
Now in my 60's I am extremely grateful to myself for taking these steps.
I don't have to worry about living or not, or will I make it later in life without money or shelter.
That is never a good place to be in, however a person must learn to accept advice from people who are successful before it's down to food stamps and Section 8 housing.
