I think she means more like, happy with little. She is obviously quite healthy and doesn't appear to lack for any of the basics.
Her point, though, is spot on and very true and powerful. If one can be 'happy' and content with 'nothing' (food, water, shelter, etc.) then they are truly blessed and can live on in total peace. :)
Here's the full vid.. I kinda of zoned out when she started talking about all the religion stuff, but I definitely agree with her first message.
thanks again to youtube for hosting this and for throwing it up on my feed to see..
