Tweet ideas to me @SmarterEveryDay

Instead of saving for my kids' college, I make videos using the money I would have saved.

The thought is it will help educate the world as a whole, and one day generate enough revenue to pay for their education. Until then if you appreciate what you've learned in this video and the effort that went in to it, please SHARE THE VIDEO!

If you REALLY liked it, feel free to pitch a few dollars towards their college fund by clicking here:

Warm Regards,
