The more website you are maintaining the harder it takes and you are overwhelm and loose of focus. Without focus your effort is wasted without any results. In the end your website will be a failure because of lack of focus.
We think that the more website we make and create the better the chances of winning. Yet without any team working together you are building a house with multiple skills required to finish in order to succeed.
The more failure you get the more wisdom you get in your failure then you need to embrace changes in order you can move to the narrow of success. If all the website are just successful then everybody are happy.
Not all website will be successful only few are chosen on the road of successful website.
