3 is a good daily limit imho. And yeah, many just download anything of minor interest to them. I am also a culprit as I also have a huge ext. drive full of crap I will never watch or read, because I also only have 24 hours a day (which must include eat, sleep, work, etc. as well). Most courses are just repeating themselves or each other. There are only a few one which are truly great. Hard to find which ones are those as it will be different ones for different people.
