I would suggest vocational training even if you have to borrow the money to get it.

You need to be tested to learn where your best-suited skills are; for example, you may be gifted in mechanical things, or things involving color and design, or math skills.

Once you have training, you begin to work at a somewhat nominal salary, I would think, and work your way into ultimately owning a business, such as Landskaperdan has done, or buy into a mechanics business hoping to own controlling interest one day.

You may be surprised what skills you have after you learn the results of testing.

Whatever you decide to do, your best opportunity will lie in getting training for it first and knowing that you have to work your way up the ladder. The more education you have in your field, the better chance you have of financial growth and enjoyment in that line of work.
