It all comes down to motivation and hard work. A friend of mine is a nurse. He doesn't look anything like the stereotype of one. A side hobby of his is working on old cars. He made his own parts in his home garage, then when other friends wanted parts, he rented space in a corner of a machine-shop. His business grew over the last ten years as he expanded and hired others and leased his own building. It is now his full-time job, making custom metal components for old cars.
Having a degree is nice, but there are cheaper ways of obtaining one than going into deep debt. Meanwhile, you can still make a decent living with or without one (by living within your means).
Our daughter has a best friend from WI, and her parents started a business that manufactured reloading equipment. They weren’t really big, until zero got elected. They went from a handful of employees to over 100. They’ve had to expand their facility three times since 2008. They used to ship the day an order came in, but now have a 2 - 3 week wait time to fill the orders. Their daughter quit a $65K job in CA to help with the business.
My wife has a good friend whose husband has run a gun magazine manufacturing business for years. He has a similar story. His business can’t keep up with orders. Some of his magazines are also used by the military as well. Got to say one thing, obummer has helped anyone who has a firearms related business.
