Answer:
I developed my soft skills of communication by talking to my friends often - I offered advice when they needed, constructive criticism when I noticed there were important things they needed to work on (of course, after being asked for feedback), I was able to tell how they feel based on their body language alone and help them out when they needed help.
As a high school student, I also had a lot of opportunities to do public speaking in front of my class which I believe improved my soft skills significantly and made me more confident in myself.
Thanks to various school assignments, I developed and improved my critical thinking which is crucial for any job in the future. I believe I am more independent now and can make sensible decisions on my own and/or as part of a team. Teamwork is important, which is why I worked hard on developing that skill as well.
I am always willing to learn and improve, which I believe is an important skill any employee should have.
