Do you know that feeling? You lie awake at night, toxic thoughts take hold of you and you can't get rid of them. They become more and more powerful, while everyone on Instagram is smiling. While the shelves are overflowing with happiness guides and positive psychology and a whole happiness industry is booming, and while life is good to everyone around you.

People don't talk about those nights. And they don't talk about the sentences that really dent your self-confidence. That doesn't fit in a world that only demands good vibes. In which the pursuit of happiness has long since become a compulsion to be happy. If you can't find your way to happiness, it's your own fault, you haven't worked hard enough - and it's better to hide.

There we have them: the 100 royal roads to misfortune. You will realise that you are not alone with one or another destructive thought pattern. There are also sentences in other people's heads that break through mercilessly. We do not decide what we think - thoughts come whether we want them to or not. They are part of life and the realisation helps immensely, but this book can do more.

By sharing his 100 Paths to Unhappiness, Frank Berzbach helps you to recognize your own toxic thoughts and drag them into the light. You can learn to step back and decide how to deal with them, thereby taking away some of their destructive power.

"Bad, negative sentences are forming in your head, and in mine too, but that is not unhappiness. They only become the royal road to unhappiness when we believe them, give in to them, and confuse the thoughts in our head with the reality outside."
