As a full-time investor, first of all, you must have a certain capital and good performance before you can consider being a full-time investor. Otherwise, you are likely to give up, because you need to bear too much pressure, just like the pressure on money is everyone's biggest worry.
When you are a full-time investor, you have to think like a boss doing business, and then make your funds bigger, how to manage your funds well, and then keep making money (win more and lose less).
