If he doesn’t want to go to university, it would be a good idea for him to study a business course at a local college and get some work experience under his belt. Being a successful self employed person is about so much more than just having a good idea - and if he doesn’t have an idea that’s not a good sign. Is he basically saying he wants to be his own boss and not take orders from someone? I’m afraid that successful self employed people aren’t their own bosses - they are wholly subject to the demands of clients and founders, they work all hours and have no paid holidays or sick leave. Without a good business plan and some experience he won’t get funding and few start-up businesses can survive without that. I think you need to have a serious talk with him because he’s not living in the real world. All the technical ability in the world won’t ensure success if you’re stuck for ideas about what to do, can’t get funding and have no way of paying for the basic necessities in life.
