I would think the best way would be to start out with a large sum of money and invest it conservatively. If the initial sum is large enough, your investments will yield a lot of money quickly.

Do you have access to a large sum of money?

If I did, I probably wouldn't be asking how to make money quickly.

Well you should have stated that clearly in the initial prompt, I'm not in the business of making assumptions.

You're correct. I meant my response as tongue in cheek, though that didn't really translate well in text, my apologies.
