The Internet is now everywhere. In school, in crime, in entertainment, in bullying, in information, in work, in fraud, in power, and in death. It's on mobile devices. In our hands. In the hands of children and friends, teachers and colleagues. It is everywhere, it is complex and contradictory.

Being a parent, teacher, or professional today requires managing unprecedented balances and new skills. Ready-made recipes don’t work well because the Internet affects almost every facet of our existence and changes like lightning. It is time to talk about online living and its main components.

Simply advising "a maximum of two hours on the Internet and keeping the computer in a central location" is not enough. Because time may be insufficient or catastrophically abundant. Because our children are online through their classmates' phones. And from anywhere else they wish.

In this book, we therefore highlight the essentials about the Internet that every parent, teacher, and user should know. Each of us. What can happen to me and what can I do in life with the Internet. With tangible examples, in a context of safety and creativity.

Life remains outside the Internet, but it can become better or worse through it. And that depends on us as well.
