This happens when you know little and yet you aren't aware of how little you know.
As a kid I self-learned photoshop and always struggled with coming up with projects to do with my knowledge.
Little did I know photoshop is a tool, not an end.
Web development is a tool. If all you know is how to hit with a hammer, it is pretty hard to make good use of it. You need to learn how to build a house, then your knowledge of a hammer will become a useful tool for accomplishing a well defined task.
Knowing how to build a house is much more difficult and isn't a 'side project' for most people. Hence the solution to your problem is realizing how little you know, how much it would actually take to create anything remotely useful, and moving on to learning something easier that'd have an actual impact in your daily life, such as exercise, a new hobby that'd foster new meaningful relationships, etc.
One last thing - if your motivation for a side project is money, you're kidding yourself - just go enjoy your life :)
