+        Over the first five weeks of Dev Academy, we have learnt a lot about the basics of HTML, CSS and JavaScript. We also 
+        spent a lot of time learning about "core" concepts. This "core" learning was focused on learning about our soft skills, 
+        about constructing learning plans, working with people and managing our minds. This post is all about looking back on 
+        some of the core concepts that I have learnt in the past five weeks.
