The book is fairly old and does not need any review as such. I read it recently; some of the things are definite value adds. Emotional intelligence can be applied to improve in the following five areas:
- Self-awareness
- Self-regulations
- Motivation
- Empathy
- Social Skills
While most of it may seem common sense, practicing may take time. As a practitioner, one can apply these in personal and professional areas to improve these skills.
