One option is to start a small business to provide a product or service. It is permissionless so it won't matter if you have a degree or not. You can also leverage resources such as capital and human talent later so that you don't need to worry too much about being smarter than average. Most rich people or business owner aren't smarter than average. You do need to be relentlessly resourceful though as written by PG.

Alternatively, it is never too late a go back to school and get a degree. Bootcamps may also work. Try to build (open source projects) or generate content (like teaching people to code in youtube)
