Like studying programming languages, to succeed with AJAX/JSON, you will need to spend a lot of time practicing your skills. The more bugs you run into, the better developer you become.

You will have to find good study materials, good teachers, and a good community to help you when you get stuck. Most importantly, you will have to find the discipline to study and practice and improve regularly. If you don't study regularly, you won't make much progress, or worse, you'll make lots of progress and then forget what you've learned!

You will also have to build something from scratch. Tutorials are great, but your skills really improve once you challenge yourself to build something on your own.

You see, most people only focus on watching tutorials. If you wish to become a great developer, you need to challenge yourself to build new, complicated projects and spend enough time with each so that you see regular progress and improve your skills.

Bottom line, if you want to become an AJAX/JSON developer, do this:

Do these things regularly, and within 1 year, you can almost certainly be well on the road to becoming an expert in AJAX/JSON. The question is: will you actually do these things? Ahh, that is the question. We hope you will!
