Do you find it hard to resist checking your smartphone more than it's actually necessary? Do you know the real costs of this "relationship" you have developed with your mobile device?

If you're an avid smartphone user then these questions should concern you. Unless you want more from life than immediate gratification through constant Facebook interaction, playing games, reading stuff online, taking selfies, and keeping yourself entertained thorough gadgetry you have no reason to read this book.
