To study, or not to study, that is the question

I finally am back to working fulltime. Great for my family, not so great for study time.
If I only worked and did not have girls to watch as well it would be easy, full time working plus full time dad = not much free time.

The question is, do I spend what little free time I do have studying? or rotting my brain in front of the tv and on the internet....... we will see....
