How should I choose between a customs declarer and a foreign trade salesperson?

I have been working for three years, and I feel that after working in an industry for a long time, we will become disgusted and tired, because we work for life, not live for work. Since you are working for a living, of course you must choose a job with a high salary and a promising future. The job of a customs declarer is relatively fixed and the salary is relatively fixed. Of course, the work pressure is also relatively low. Salespeople have a lot of room for development, their income is uncertain, and their work pressure is relatively high. You have to think clearly whether you are more tolerant of stress or prefer stability. Then decide what you want to do. No one can give you the final decision, only you can decide.
