I've selected for you three little videos. The first one to share with friends who don't know what ideation is,  and the two last ones are TED talks that can inspire you.

In this short one minute and thirty seconds video a coach from The Art of Education University gives a quick answer to this simple question. Great to share with friends and colleagues who don't want to read a whole book or course like this one.

This is a 16-minutes TED talk by Manoush Zomorodi. The speaker explains the connection between spacing out and creativity.

This is  a 18-minutes TED talk by Steven Johnson. The speaker explains with historical examples from where ideas come from and breaks the notion of the Eureka moment.
