Get started in the right way by checking you are holding and strumming the guitar using the right technique.
Key Points
Sit in an appropriate chair, not slouching on a couch
Balance the guitar on the thigh at the same side as your dominant hand (right handed? Right knee!)
Hold the neck between your thumb and forefinger
Remember to track your progress with the Strumming Family Tree, which is in the pdf ebook that accompanies this course.
