I had social anxiety and often kept to myself, I became very introverted and often stayed at home instead of going out with friends. I would read or stay in my room when guests came over.
I wanted to try and become more extroverted so, I joined the volleyball team in high school. I made many new friends and even joined some clubs. I started to go out more and, it became easier for me to talk to other people.
Trying out for a sport and joining clubs have allowed me to branch out and work on my social skills. It's allowed me not to be so nervous about job interviews and helped me start conversations with customers.
