This was a question I was asked on Quora. Here is my answer:
You Can Be A Millionaire
I will answer your question first, which is the hardest way to be a millionaire and then I will tell you the much easier way. Last, I will then tell you one more way.
Hard Way-Do You Constantly Think Of New Ideas
If you don’t naturally think of new ideas, it will be extremely hard. Most inventors are not rich, but they have many ideas, hundreds or more. Some are good and most aren’t. But they don’t even have to try, their brain is just wired to see it. The problem is they don’t know how to develop them. Plus before they get one idea flushed out, they have another idea. Focus is tough.
Read the books on how to generate new ideas. There are no new ideas, just tweaks on old ideas anyway. I suggest you read Borrowing Brilliance, this is a very good book on changing your perspective on how to generate new commercial ideas. For the grinding, making lists, asking people, read problems before you go to sleep and then write down answers when you wake up-then read How To Get Ideas by Jack Foster. Plus I agree with the list in the post below.

You don’t need as much money as you think, you can get a piece of many startups for a song, $10,000 or $25,000. Plus you can always raise the money deal by deal if you want.
