Regret being a security guard and don't know what to do.

Hello, I think since you can know regret, you must not be numb to make a comeback. Choosing security as a career is a relief. Not many things are done every day, and the salary is not high. When I was young, I could live alone. After I get married and start a family, the pressure of life will inevitably increase. At this time, there is no skill in hand, and it is more difficult to change careers. So I suggest you learn to be a chef. You can still make rapid progress in a year and a half. As long as you work hard, you will develop in the future.
