You get what you pay for.
Unless, someone else has paid for it!
Well, someone is paying for this:
Free lecture notes, exams, and videos from MIT.
And some pretty great stuff.
World class education available to anyone.
So many great applications.
I'm currently working through The Nature of Creativity.
I've also been thinking about joining the local gym.
It will be nice to know the proper form for the Stiff Legged Deadlift.
Have a look at the course offerings.
Which would be your dream course to take?
