More importantly, you will need to put in some effort (energy) to achieve results. Will you earn while you sleep? Don't believe that hype! The only way you can earn while you sleep is to put in the work while you are awake!
Be sure to do your own due diligence before you part with your money and check the bona fides of those with whom you will be doing business.
Thousands of people are flocking to the internet everyday in the hopes of making extra income, or to make a full-time living online.
Can it be done? Absolutely. But there is far too much hype about how easy it is. If someone tells you that even a child can do it, don't believe them. If they tell you it's so automatic, hands free, passive, you don't have to do a thing (except, of course, open your wallet and fork out the dollars), don't believe them.
You will be able to create passive income that runs on autopilot. But what you are not told is that initially you have to do a lot of groundwork, a lot of basic business building and honing of your marketing skills, before you can reach that magic point where you start earning residual income "passively".

It takes time, effort, persistence, and continuous learning and improving your internet marketing skills to keep pace with the rapidly changing environment of making money online. What worked yesterday may not work today, so you have to keep abreast of the trends and what's hot and what's not. Nevertheless, basic business building priniciples always apply and you cannot ignore them.
At the very least, if you are really serious about earning from the internet, you will need to have:
1. Your own hosting account
2. Your own hosted web pages (it doesn't have to be a full website)
3. An autoresponder
The internet is not magic, and it will not spit out money like an ATM machine. However, if you have a systematic approach and the right tools, and the right mindset (work ethic), you can and will succeed!
