I was determined not to post any more videos because the site is loading too slowly. This talk on the importance of play is too good to pass up and too spot on for what I've been blogging about recently (finding joy). So please enjoy and then go out and play!
Update, this video is no longer available, but you can hear him talk here https://www.takingcharge.csh.umn.edu/practice-play-dr-stuart-brown
