Impromptu: How to Think on Your Feet
by Grenville Kleiser
A Practical Guide to Speaking with Confidence and Readiness
Impromptu: How to Think on Your Feet by Grenville Kleiser is a classic self-improvement and public speaking guide devoted to the art of speaking effectively without extensive preparation. Written by one of the early twentieth century's most respected authorities on communication and oratory, the book provides practical advice for developing confidence, mental agility, and the ability to respond clearly in unexpected situations.
Kleiser believed that the ability to think and speak spontaneously was not an inborn talent reserved for a fortunate few but a skill that could be cultivated through practice and discipline. His work seeks to help readers become more articulate, persuasive, and self-assured in both professional and social settings.
The result is a timeless manual on effective communication.
The Value of Impromptu Speaking
In everyday life, people are frequently called upon to speak without advance notice. Business meetings, classroom discussions, interviews, social gatherings, and public events often require individuals to express ideas quickly and clearly.
Kleiser argues that success in such situations depends upon the ability to organize thoughts rapidly and communicate them with confidence. Impromptu speaking is presented as a practical skill that can improve personal effectiveness and professional opportunities.
This belief forms the foundation of the book.
Developing Mental Readiness
A central theme of the work is the importance of mental preparation. Although impromptu speaking may appear spontaneous, Kleiser emphasizes that readiness is often the result of continuous intellectual development.
He encourages readers to cultivate habits such as:
- Regular reading and learning.
- Careful observation of daily events.
- Organized thinking and analysis.
- Practice in expressing ideas clearly.
These habits help create the mental resources necessary for effective spontaneous speech.
Overcoming Fear and Self-Consciousness
Many people find unexpected speaking situations intimidating. Kleiser addresses this challenge by offering strategies for managing nervousness and building confidence.
He suggests that fear often diminishes as experience increases. Through repeated practice and a focus on communicating ideas rather than worrying about mistakes, speakers can become more comfortable addressing audiences and responding to questions.
This practical approach makes the book especially useful for beginners.
Organizing Thoughts Quickly
One of the key skills discussed in the book is the ability to structure ideas rapidly. Kleiser explains methods for identifying a central point, selecting supporting details, and presenting information in a logical sequence.
Even in situations requiring immediate responses, clear organization can make communication more effective and persuasive. The book demonstrates that successful impromptu speaking relies as much on thoughtful structure as on verbal fluency.
This emphasis on organization remains relevant today.
