I use to be like that. But I found that once I cancelled cable, my habits changed, and now I prefer to watch exactly what I've been looking forward to. Although not everyone will accept that change.
Three years into no cable here. However I probably watch more TV now, it's just only EXACTLY what I want to watch. With my MythTV dvr and Ted, I don't miss a thing.
HGTV and Food network were my time sucks, hours ago by before you notice.
