I graduated for seven years. What I regret most is the detour I took. The first job I applied for after graduation was clothing foreign trade documentary. At that time, I didn't know much about this job, thinking that I was just carrying boxes around like some merchants. So I gave up this job. After six years of turnover, I have worked as a clerk, secretary of the board of directors, secretary of the president, translator and foreign trade business. Six years later, I re-entered the clothing industry.
I think the landlord's current job is very training, especially in bringing guests, which is very helpful for your social interaction. You are an introvert, you can't avoid it, because now society won't open a window for you because of your introversion. Now it's up to you to adapt to society.
Making spreadsheets is an essential basic skill for you to adapt to the present society. You must understand whether you are engaged in clothing sales or clerical work.
