Adults are obsolete children, and the hell with them.
Children learn as they play. Most importantly, in play, children learn how to learn.
Toys are children's words and play is their language.
Toys are the first tools children use to understand the world around them.

You can't direct the wind, but you can adjust your sails.
The only way to do great work is to love what you do.
Play gives children a chance to practice what they are learning.
