Without college your best bet for a good living is being your own boss in a blue collar trade. You'd probably have to work as an employee for a few years to get experience. But don't waste time as an employee unless it is a business you want to make a career out of.
I'll give a personal example to show that I have some credibility on the subject. I started as a locksmith employee in 1979. I started my own locksmith business in 1982. I live in a county of only 20,000 people & average 5 hours of work per day. Over the last thirty years I have managed to save about $14,000.00 per year & I have $430,000.00 in assets with no debts. None of this came from investments as my investments lost me more money than I made. Just putting money in bank accounts worked for me.
One more thing...don't get married if you want to protect your assets. I did marry & divorce 20 years later but I got very lucky in the financials of the divirce. Most men won't get so lucky in a divorce.
