I don't know what the landlord's interests and personality belong to. If you like to deal with people, have a wide network of contacts and are interested in finance, you can try to sell securities and futures or bank cards, and so can a gold salesman. In fact, they are all the same, allowing you to open an account with relatives and friends for performances or visit strangers. If you are introverted and simply like trading, you'd better not do any American stocks, work hard and study securities in your spare time. If you think it's horizontal.
Why do you suggest this? Because of the high elimination rate in the securities market, you think you can succeed, but the fact is cruel. Now you give up your stable job and trade full-time, and the result is probably nothing. If your job is stable, the income from stock trading is higher than your job income, and you have three to five years of stock age, you have experienced different markets, and your mentality and skills are relatively mature. At this time, you will be confident to consider quitting your job and joining the securities industry.
In fact, I don't recommend that you do both jobs now, and the elimination rate is very high. It's almost a year since graduation. I dare not give you any good advice, but at least I know something about these two jobs. Financial sales sell intangible products, whether it is insurance, securities, futures or gold, which are not so easy for the public to accept compared with physical objects, and are good for one's eloquence, mind, professional knowledge and sales. So I suggest you think carefully and don't step into this business until you are fully prepared.
Your specific situation is not detailed, so I can't tell you too much. Let's talk so much first. Good luck.
