A real project is an excellent way to pick how to do web development.

Have you got any hobbies or interests? Why not create a website dedicated to your hobby/interest? That way it'll be something that you'll be able to run over the course of a few years.

Start with a small website, and slowly build it up. Add more features, then tweak them. Find out why it's loading slowly. Read a few books on website that scale too.
