Curiosity is a valuable skill. It's important to be curious about how things work, what others are like, and how other people solve problems.
Curiosity is indispensable and required in the 21st century - it gets you excited about new projects, and it also keeps you going when things get difficult.
Sometimes it's scary to learn something new. But once I've pushed through the fear I'm always glad I did.
Find a way to cultivate your curiosity: take a class that interests you, read a book on a difficult topic, talk to someone you wouldn't normally talk to.
If you come across someone who isn't curious or doesn't want to learn something new you should ask why and be curious about that. Maybe you can help. We all have times where we struggle with change.
