Just because he is adventurous doesn't mean you have to be. Everyone is different in their own way. If you're looking for something to do outdoor why not go on a hike or pick up a new hobby?
I have a friend who is really adventurous. He never seems to be afraid. He gets opportunities to do awesome things like hot air balloon rides. He goes to different states. But my family doesn't do things like his does. What should I do?
