Everyday we study and work, or are busy, throughout the day. Then, as it gets later we get tired and our brains don't work as well. Usually during this time if we are alone, we watch TV. The easiest way to spend this time is watching TV shows in our first language, it is pretty much impossible that we would really study, or use a grammar based website, or watch a video about grammar or vocabulary.
The key is to find a TV show on youtube that is about a topic you really care about. For me I love the NBA, so I tune in every day to see a twenty minute episode, its called "The Starters" on NBA TV. They talk about recent news on twitter or in newspapers, they discuss the performance of teams and players, and there are also random jokes. Because they have to make a new show everyday, each section is very structured. The hosts say introduce themselves in order, and three of them say the same thing each episode. There are a number of segments including: trade winds, trend or dead end, cross fire and the "very solid play". Once you have seen a few episodes the general structure and the rules for each topic become clearer.
If you are really interested in basketball you will really want to get the information, the listening will not feel like study, you will simply be trying to get the information. Language won't be about form, but about meaning. Watch these kinds of shows about the topics you are really interested in to work on your listening when you are too tired to do anything else.
