Resources to improve my economic intuition I am trying to improve my economic logic skills and ability to think about day-to-day issues in the systematic way economics and decisions science approaches scarcity or optimization.  

A simple example to clarify, I know that MC=MR however the intuition as to why MC$&lt;$MR is not optimal is something which educators seem to overlook to explain. 

I am looking for any resources online or textbooks, workbooks, non-fiction, etc that will help me sharpen these skills. 

Let me know if I can further improve my question, apologies in advance as this is my first post.
While textbooks are the best way to learn the material (MC=MR etc), here are some suggestions for improving your intuitive understanding of economics.
