My first job was the hardest assignment(任务) you can get. I spent my first year there teaching math in a middle school, and the following two years I taught at the Academy of Science & Engineering. When I spotted a job opening within the high school network Soledad Enrichment Action and I saw the students, I knew it's where I wanted to work. I'm in my third year there, and I love it. It's so much more satisfying than what I used to do for work. The best is when you see a student really getting something for the first time. Especially algebra, which can be very confusing. Sometimes I was so confused at their age that I couldn't even ask a question, so I know that feeling.

I feel relevant again, like what I do is really important. I don't plan on ever retiring.
