May I suggest two books: the intelligent investor by Benjamin Graham and Rich Dad Poor Dad by Robert Kiyosaki. Improving oneself may open new doors. If you’re already into real estates and the stock market, those are huge hustles. Many ways to gain huge multigeneratio nal wealth from it. I don’t recommend Uber, lift, taxi services, you can’t control who is going to step in your cars.
I haven’t gone passed the stock market. Real estates is my next endeavor, maybe hotels, commercial is my aim. At the moment real estates is overvalued, can’t see it sustaining too far into the future.
