+  Make the change easy, then make the easy change.
+---
+
+This week, I've been working on a particular component that processes and displays live data from APIs.
+
+As the data is live, it's constantly changing and it's unlikely I'll see all the different states and use-cases that the data could be in.
+
+There's also no guarantee the API will be available and I also may need to work offline with no Internet access to connect to the API.
+
+I'm reminded of the quote by Kent Beck:
+
+> For each desired change, make the change easy (warning: this may be hard), then make the easy change.
+
+In this case, to make the change easy, I need the data to be consistent, to see all the use-cases and permutations and to be available offline.
+
+To make the change easy, I created a fake version of the service class that returns static data I can work with.
+
+I can add whatever data I need to give me the examples and situations to work with and by implementing the same methods as the real service class, I can swap them without changing any other code.
+
+Now I can make the easy change.
