The best scientists and explorers have the attributes of kids! They ask question and have a sense of wonder. They have curiosity. 'Who, what, where, why, when, and how!' They never stop asking questions, and I never stop asking questions, just like a five year old.
I love music of all kinds, but there's no greater music than the sound of my grandchildren laughing; my kids, too.
Scientists never stop asking. They're little kids who never grew up.
