Hi there,
To echo MindMax 2000, starting a business can be incredibly risky for anyone - even for someone who has all the qualifications in buisness. It involves a lot of research and takes up alot of time to understand the market and what you need to be sucessful.
If you are not interested in university or an aprenticeship, I totally understand but learning never stops. What might be useful is to take courses in business you might find useful to help you start your business. Different Universities provide invidiual courses directed at individuals not interested in completing a program but would like some information. It would be useful to get experience in managing finances, computer software that you could use, conflict management, and any skill based course which could enhance the business.
Starting a business is not for everyone (I know I could not do it). However, I think with the right resources you could develop the skills to better your chances at success!
Good luck and happy to provide more context.
Thank you,
