How can I earn extra cash working from home? -

if internet is the answer doing what?what other things could generate money from home?

You need to send your resume out to real jobs you are qualified to do. In your cover letter you need to state that you wish to work remotely, from your home office. LOTS of companies, especially in CA operate this way. They usually provide transportation for you to come in for an interview and for you to attend company meetings a few times a year, but otherwise everything is done online.
