How to Develop Self-confidence and Influence People By Public Speaking (Tankobon Hardcover)

This book has a classic approach to persuasion and confidence. I wonder what personal experiences or observations led him to emphasize speech as a tool for influence.

Some techniques felt very 'classic'—are they still effective today, or would modern audiences need to adapt them? Curious about others' experiences.

The anecdotes are memorable but seem carefully chosen. I wonder what process he used to select stories that resonate across different audiences.
