Always learning?

I'm finishing another set of free lectures available from Yale Courses as seen on YouTube and Open Culture.  These video lectures are what I term lite learning as they do not require interaction with anyone else nor any additional cost other than my time to listen to the lecture.  However, they are learning in that I'm covering material I either never had time to take before or have forgotten the basics. 
I used many of these basic lectures for reference purposes as a way to help with undergraduate research.  When we move beyond the basics, we often forget what is not Old or lite or basic is new to those just encountering them. 
These may be considered 'lite" from another perspective.  The courses I chose are based on my own interests in the humanities rather than required learning in the sciences and math. Required courses really are the grindstones which help even out a student's grasp of the surrounding world. Another way of putting it is  one might find that one is driving on 1 superinflated tire, two relatively even tires, and one highly flat tire.  While that's metaphor has flaws, sometimes undergraduate education is the attempt to make the tires--so to speak--relatively even.

So here's to the Yale and Harvard lectures with a deep thanks to other "free" courses which I've been looking and listening to over the past year.  Thanks for engaging me enough to continue on with other readings and reflections.  I hope to keep reviewing them and enjoying them for a long time to come.
