Not everyone has the maturity, skills, ambition, or passion to work for themselves or start a business. Especially at 18 years old, very few people actually have a clue about what they want to do when they grow up, you know, that old maturity thing rearing its ugly head.
Spending a few years learning how to learn, learning new skills, meeting new people, developing new relationships, and learning new interests has a very beneficial effect on many people. It doesn’t have to be a higher education at a university level, it could be a trade school or professional school level. It could be an internship or apprentice type of experience. Just go out and experience, learn, observe and get a clue about real life.
Remember, in the real world, having an education or not having an education has no effect on getting rich, and not everyone only wants to get rich. Some people have other priorities in their lives.
Getting rich requires hard work, ideas, skills, planning, and execution to do it and based on the new business failure rate, obviously, not everyone has what it takes.
