Hrm, I think you're forgetting about the most important money making tool available: compound growth. Let's assume the following: You invest your current 24,000 and each month you add 20,000 to your investment. Let's further assume that you can achieve an annual return of 3.5% and that return is evenly distributed over the year. In this scenario you'd end up with $520k after two years. You're half way to being a mill…
As for your problem, do what most people say here: invest in the best asset you know: your business model. If you are very lazy, then just simply figure out how to let someone else do the work.
And I wonder if you meant that question seriously? The wording sounds awfully naive.
