Some people like to read loads of books and blogs for the sheer pleasure of collecting knowledge.
But those of us who want to maximize the utility of the knowledge we come across in books and blogs have to understand how to integrate this aforesaid knowledge. That is, we have to know how to apply this information and make it part of our daily lives.
For example, there’s only but so much you can gain from reading about strength training You can learn what movement patterns exist, different kinds of stretching, and programs but you have to actually get in the gym to make any physical progress.
The same goes for everything else. You have to actively apply and integrate the information you absorb. You have to make them useful or the information will evaporate.
When I was in undergrad, I learned the basics of 3 programming languages, C, C++, and Python. Due to the fact that I learned these languages without a framework, I didn’t make practical use of them. My guess is if I had to build a project using these languages they would have stuck.
At the end of the day, reading, earning degrees or listening to podcasts will bring you but so far. It’s about how you can extract the pertinent information for meaningful application and integration within your everyday life.
