根据下列材料，请回答题：Walk Out of the Comfort Zone and Try New Things
For most high school students, free periods are useless. From what I have seen, few do homework, instead many are on their phones and talking, making it impossible for those who actually want to do work to complete any. As a senior next year, I think extra periods should be used to take optional subjects.
Our school offers many classes. Now is the time to experiment in different fields of study. We will never know if we are interested or talented in a subject if we don't try it.
In my 8th grade, I was told that I had to take an art class as a graduation requirement; so in the 9th grade I took Studio and Art. One of the projects was to build a clay pot, but I built mine incorrectly, so it broke in the kiln (窑). I found out that I have no artistic ability at all, and now I know for sure that I do not want to be an artist. However, the class was one of my favorites that year. I was able to try new activities and test my ability.
Walk out of our comfort zone and try new things! College is when we should focus on a specific major, but high school is when we have to figure it out.
Half of all college students change their major at some point. By doing that hundreds of dollars are wasted on classes that they would have never needed to take. So use our extra periods to find out what we want to do in college. The classes we choose can impact us in future. Taking optional subjects will enrich our mind. It will also show colleges we are diverse students.
How should we use our extra periods in the author's opinion?
