“The Courage to Be Disliked" is a popular self-help book by Ichiro Kishimi and Fumitake Koga that explores the concept of embracing our true selves and living authentically, even if that means being disliked by others. The book is based on the principles of Alfred Adler's psychology and offers practical advice on how to develop the courage to be ourselves without seeking validation from others.

Some key takeaways from the book include:

1. The desire to be liked by everyone is a major source of unhappiness.

2. You don't need to be liked by everyone to be happy.

3. Being disliked by others doesn't mean there's anything wrong with you.

4. Embrace your uniqueness and don't try to conform to others' expectations.

5. Take responsibility for your own life and choices.

6. Don't be afraid to express your own thoughts and opinions.

7. You can't control how others think or feel, but you can control how you respond to them.

I think "The Courage to Be Disliked" is a thought-provoking book that encourages readers to embrace their individuality and live a more authentic, fulfilling life.
