Studying news is important, but spending too much time is not ok.
One should study and get knowledge and then try his/her best to use that knowledge.
If we are getting knowledge and not using that in any part of lift-time, then it seems useless.
Everything should be viewed in sense of usability, that is how much we are using it.
This will help us to prioritize our activities and studies, and prevent us to spend time on useless activities/studies.
