This has worked for me. By dropping cable for netflix and hulu....I end up spending more time usefully.
Streaming only what you actually want to watch is a great way to limit the time you spend watching things, especially with Netflix as there is never anything you want to watch on it.
I too find it difficult to find things on Netflix to watch, but I can get lost in video podcasts for far too long. There is a lot of great programming suitable to my tastes there.
