Even if you don't know anything about the internet you can still be successful online. It is unfortunate how often I see people discouraged from liberating themselves from their day job because they believe that the internet is a platform only for the few gifted ones. The learning curve online is in a lot of ways simpler and quicker than what one might experience in learning the basic ropes in a new job that they are already qualified for. In other words, you still need to be shown where the coffee maker is and the bathrooms as well as where to file things etc.
The sad part about people missing out on this incredible opportunity is that they don't believe they can do something that is much easier than most of things they have already been doing their entire life! The present system has been encouraging a mindset of relying on employers for one's livelihood. There is no freedom in this way of living and one must be willing to accept not understanding everything before they are able to understand anything.
If you don't know anything about the internet you can still be successful online so long as you are willing to put in consistent time and you have someone helping you. There are many things online that literally take five minutes to learn and then consistent repetitive action to begin putting money in your bank account. Sometimes, the money doesn't come until after weeks or months of consistent effort but once it does, it is hard to stop. My encouragement to you would be not to disqualify yourself from making the move online as everyone that is successful on the internet started with little knowledge and we are most certainly not any better than you!
