My Medium Earnings Perfectly Illustrate Why “Follow Your Passion” Is Poor Advice

Here’s the much better advice instead — I have a confession to make. I don’t have an innate passion for writing technical blog posts. I started writing them as a way of solidifying my own learning. You know the saying: if you can’t explain something, you don’t understand it. …
