Making Friends is the best way to get you to do things that interest you. For example, I hated reading and thought books were boring. My best friend allowed me to borrow one of her books, and I loved it. Then, I learned that this book was a part of a series. Now I love fantsay and sci-fi books, and own a literial library at home. I'm not saying you need to read books, but having friends allows you to have more opitions on finding your own hobby.
For some of you, I can hear you groaning from the beyond. "I already hang out with my family, what gives?", and I understand that. However, you can get your own hobbies by just being curious about what your mother is watching, or what's in your dad's closet. You may not realize it, but just by being with your family during their downtime, you could learn so many things. For example, just by watching me watch other people play videogames-(cause I'm poor)-my sister found out she loves horror games. Now she watches them with me, and something similar has or could happened to you.
The internet is the place were you can find so many things. From articles about the world, to the greatest movies ever made. You could see new places to add to your bucket list, and find communities of people trying to help save the planet. The internet is where you can find and elaborate on knowledge that you find interesting. You can even try to find research on the internet and how it works, and how all these websites exist. The possibillties are endless, and it's all right here. Find new things, explore and have fun, don't get viruses or hacked, and keep expanding on what you like.
