You may need at least 5 years to "Fa Cai".

On the first years: you may want to read some basic books to know what's stock and what's stock market. If you find book talking about investment hard to read, you would choose other books talking about personal finance. They would give you a basic picture. When you start knowing what is it, you may want to read some deeper books and learn some investment theory and analysis skills.

On the next two years, you can start to look at stock market. Select some shares and know better about the real stock market. But never put any cents in it. During this period, you will really understand those theories and get some senses to the market.

On the last two years, you can try to invest with some pocket money. But don't throw thousands of dollars into it. 3 or 4K should be enough for the experiment. You may find actual trade will be very different from hypothetical one. After this two years, you can know your psychological strengthes and weakness and select your own investment styles.

After these 5 years, you should be very experience in the stock investment and can "fa cai" after that.

This is just my personal opinion, maybe you are very intelligent and do not need such a long time.
