One thing is for sure, there is a lot of content. Just think about it, year after year, people are writing all kinds of books and other forms of content. It does not take long for this to start adding up. There are lots of works that are created. Years and years of content has already been made.
Sometimes, there is just so much content that you can forget it. Just think about your house and if you started adding new stuff everyday. Just mountains and mountains of stuff everyday. Before long, your house would be filled up to the roof with stuff.
Taking a look back might help with thinking about the future. Just think about it like the movies. Sometimes, they go back and remake movies. The story might get a little refreshed for the current times, but there are some stories that are classic.
Looking back and looking forward is just a part of moving around. When you are in your car, you have a front windshield and a rear view mirror. They can be helpful at different times. Looking where you are going is always a good idea.
Learning from some of the older work that has already been done is a good investment of time. Trying new things is also good. So what is this all about? It is just about learning. Reading new stuff and old stuff is good. Are you up for learning from the past?
