The income of stock trading is unstable: stock trading is greatly influenced by the stock market. In a bull market, one year's income is worth several years, and in a bear market, there may be losses. You should be able to accept this kind of income instability. At the same time, your family should also understand and support your career style, otherwise it is putting the cart before the horse.
I'm actually quite opposed to people speculating in stocks.
95% of people, the result of stock trading is that the more they speculate, the less money they have. But why are stocks so attractive? The reason is that there are too many myths about making big money by stock trading in the market. People will only remember and spread those once glorious names, but they will never remember how many people lost their money because of stock trading.
The success of stock trading itself requires talents, as well as strong financial contacts and information dissemination channels. This is at most one or two out of tens of millions of people. Stock trading essentially depends on liquidity arbitrage and asymmetric information trading. Therefore, as long as people have the above resources, it is possible to survive in the market, and most people do not have this condition.
