Interests

In my free time, I like to stay active by going to the gym regularly. I also play paintball at least once a month because it gives me energy and excitement. I really enjoy sports, especially basketball and baseball.

I also love traveling and discovering new places. Right now, I’m visiting different parts of the country, and in the future, I hope to travel to other countries to learn about different cultures.

One of my short-term plans is to visit Denver, Colorado, with my wife. We want to go skiing in Aspen in January 2026 and enjoy the beautiful mountains.
