&gt; A lot of education isn&#x27;t really about what you study or where you learn. It&#x27;s about training your brain to think about things in a certain way.<p>In university I followed courses in Computing, Psychology, Law and Theology. All had different ways of learning, approaching the subject. Psychology was (for me) all about questioning: you can never be 100% sure and should always be aware of another possible explanation. This has stuck with me, and I&#x27;m champion finding alternative explanations.<p>One of my fellow students changed to medicine, and he told me that it was the complete opposite. If you questioned a method or theory (as first year student), you were completely out of line. These methods were tested thousands of times, and no stupid first year student could think of a better way, so don&#x27;t even try. I guess this changes over time because you have to change methods to make progress, but it makes clear how different cultures can be.
