As a blogger I am frequently facing a problem of not knowing what to write about. The issue comes from the question itself. You shouldn’t ask yourself what to write, you should be thinking about the problems that people have, and organize ideas on how to solve those issues, quickly and painlessly.
Sometimes the problem isn’t your laziness in action, it’s your laziness in thinking and miss-framing your problem. This gets solved when you view the issues your readers have from various different angles. And than the solutions start simply flowing, and your procrastination transforms into action.
