Becoming a investor you must get an education, have experience and have enough cash. How do you think about ?

Mr Nguyen;
I'm not sure if your question is about strait equities investing, or if you are looking at entrepreneurial possibilities. For any investing you are trying to capitalize on information assymetry, so the more you have the better. You can get online and try to gain experience yourself at places like Ameritrade or Scott-Trade for fairly cheap. You probably should also get some grounding in finance through basic text books and even community college classes.
You are no doubt from Vietnam, which leads to the second possibility that you are looking for an opportunity to arbitrage price differences between Vietnam and US. For this, you might look at current US trends, like fitness centers which are growing in China, or Branded Coffee houses which are hot in Thailand and possible examples of impending trends in Vietnam. Just read as much as you can and over time you'll be able to anticipate trends for investing more efficiently.
Good luck to you!!!

It really isn't that hard. You do need some money, but not all that much. And you don't need an education. The library offers books on the subjects as well as magazine articles. You can start in mutual funds for $1000 and they choose the investments. The most important thing, though, is to start investing. Then keep doing it!

just need good hunches or good hints, and some cash, of course

The important thing is CASH.. because you could hire people to do the thinking for you.. look at Bill Gates.. he just got windows from a friend.. he bought it for a small sum. If this world is a bakeshop, you just need to read and smell where the pies are being cooked!
