Hi jewellmari,
Welcome. It is exciting getting started online, and usually very overwhelming. It's okay to be nervous. Just don't get discouraged.
After you read through the book, feel free to ask specific questions and the different forum members will be glad to help answer them if it is something they know about.
I hope you get blessed and have quick success like Holly did, but don't depend upon it. Most of us have a slower road to success, but we can all get there in the end if we keep working toward it.
Blessings,
Angie
