The Psychology of Influence: How Entrepreneurs Win Hearts and Sales

The Psychology of Influence by Douw Steyn is a practical, easy-to-understand guide for entrepreneurs who want to attract customers, build trust, and increase sales ethically.

This book breaks down how people actually make decisions — emotionally first, logically second — and shows you how to apply proven psychological principles in marketing, sales, customer experience, and digital communication. Written with real South African business examples, it focuses on influence that builds long-term relationships instead of short-term pressure.

Inside the book, you’ll learn:

• Why customers say “yes” (and why they hesitate)

• How trust, clarity, and simplicity increase conversions

• The difference between influence, persuasion, and manipulation

• How to use social proof, authority, reciprocity, and ethical urgency

• How digital platforms shape modern buying behaviour in South Africa

• How to influence confidently without being pushy or sales-driven

Whether you’re running an online store, service business, consultancy, or side hustle, this book gives you practical tools you can apply immediately to win hearts — and sales — the right way.
