Freedom to play, freedom to think. Work with others, like this collaboration mural. The brain is plastic and it changes massively through childhood. Keeping hold of that willingness to learn and play helps solve problems, makes you think.

Memories of paddling in a river, or climbing a tree, having freedom to go to college and learn. I also think wit, and humour is important. Playing with words, striking up conversations with people. Enjoying puns and jokes, still being able to giggle. Fun is freedom to keep hold of your childhood.
