My default suggestion for drawing in a reader is to start “en media res,” that is, in the middle of things. It tends to arouse curiosity; however, it isn’t the only way to draw in a reader. Writers like Tolkien, Irving, and Shakespeare prove the point. Other writers would say that the magic is in the title. In the online world, they’re probably right. The title and accompanying visual elements are essential to drawing in the reader.
I’m a type 1 diabetic. My life consists of data points: checking my blood sugar multiple times per day, counting carbohydrates, accounting for exercise and stress and lack of sleep, regular visits to the endocrinologist, basal and bolus and correction rates, the A1C (a three-month average of blood glucose readings) and other lab work. It’s a lot of data. Overwhelming at times.
