Alright, then. The exercise is actually rather easy. First, you need to find your master. Be specific with what you want to learn. For example, if you want to learn about job interview materials, find one that you think is really, really good. If you want to write a meta post, find one (or lots of them) that you think is really, really good.

Let's say that you found and now have the master materials. Here is the task that you will need to do every day. At least until you can feel the improvement.
