I've written before about the Khan Academy. Watch the video above and see how thankful this young man is to Khan Academy and how it's changed his life. And no doubt, he will be changing others' lives too.
I'm studying Khan's videos myself and I'm hoping to become a coach for some of my neighbor's children, and also I'd like to learn chemistry, physics, and higher math.
This sounds crazy, buy I'm enjoying learning this. This is what brings me joy.
