I would like to apply for sales representative positions. What would you recommend?

For example, I would like to work as a sales representative in a retail store. I think it would be a more social and safer job.

I am a hotel receptionist. I am tired of night shifts and dealing with criminal-type people.

Do you think I could become a sales representative? What kinds of challenges does the job have? What advice would you give me?
