阅读下文并回答问题。

There are many advantages of becoming a professional musician. The biggest advantage is being able to do something you love. You will have the chance to travel to many different places and meet a lot of different people. That will open up your eyes.

However, there are also disadvantages of being a professional musician. One of the biggest disadvantages for most musicians is that they don’t always have enough money. Most of the time, you will be looking for jobs. Sometimes you won’t be able to find a good job. Another disadvantage is the place you live in. If you want to be a musician, you usually have to move to an area that has a lot of jobs, such as New York City. The cost of living in these areas is usually very high. The third disadvantage is that you can’t have a stable (不稳定的) family life. Different jobs will take a musician to different places, so most musicians are unable to have a regular (正常的) family.
