There are several abilities that I need to have to make me good at the job. Flexibility is one of the most essential elements for me to face the different challenges.As I mentioned, under-developed countries may have a worse environment than that in Hong Kong. I have to be adaptable. Also, patience is not excluded. I need to be patient to my patients for most of them may not be educated so I have to explain a lot to them. Furthermore, If I am sociable enough, more people may like to approach me. They may share their difficulties more willingly
