You've already proven that you are capable of doing great things. Work to increase your capabilities.
To generate wealth, in my opinion it's best to do things that are aligned with what you are interested in. Since you have demonstrated ability with business and technology, and some capital, start with that.
One way to generate wealth is to start a company, then sell it. There are many skills necessary, but the essential one you already have - being able to just plunge in and do it.
I'd say, dive in and see if you can learn to build a small company by bootstrapping it - without taking investment money or going into debt... take it slow and incremental, not going into debt or taking investment unless you think you have a winning team and product. Usually at that point you don't really need investment, but can use it to expand a lot.
These days, software development done by yourself or a few friends and servers in the cloud are so cheap that you can build whole software or software-as-a-service companies with your existing cash flow. Learn the technical and business skills you need. Plan experiments that help you learn - that won't kill you if you fail. You can learn much more from failure than success, so make mistakes as fast as you can.
Oh yeah, and find a good accountant and make sure you pay your taxes.

My bible on how to learn customer problems and turn them into money. Also has a great annotated bibliography of other good books to read, and a methodology for becoming a self-taught entrepreneur.
