Hello Friend,
It's nice to learn about your interest in shorthand. If you know your strokes, outlines, and short forms well, then it should not be a problem for you. You can practice by listening to the news channel and taking down their headlines in shorthand. Later, you have to read it back (that's important).
Try this, and you will see the wonders of practice. Remember, it's just practice that makes one perfect.
Best regards,
