I used to watch/listen to books and podcasts at 1.5-2x speed in order to save time and be more efficient. I took pride in thinking I was "smarter" than the typical consumer because I was blowing through tons of content. 

However, I started to realize that I was not ingesting what I was listening to, particularly when I was multi-tasking. Ask yourself, if you attended a university lecture on mathematics and macroeconomics, how much would you learn if you were doing pushups and box jumps at the same time? 

The podcasts and books that are online today are incredibly valuable and I took this for granted. My goal now is to sit down and listen/take notes on one podcast episode per week, digest the information, and be able to summarize the content to a friend, in a few key talking points. Learning isn't about chasing degrees and certificates... We need to normalize giving ourselves TIME to think deeply about what we've learnt but also the SPACE to determine what it actually means.
