25 Summers by Stephan Schäfer is a life-affirming self-help fable — a word-of-mouth sensation in Germany, with over 130,000 copies sold.

Blending storytelling with real-world insight, this book invites you to look differently at your time, your choices, and the life you’re building.

At its heart is a simple encounter: a high-achieving man meets Karl, a potato farmer, whose quiet way of living begins to challenge everything he thought he knew about success, relationships and what really matters. Through their conversations — warm, direct and often disarmingly simple — a new perspective begins to emerge.

Warm, wise and deeply human, 25 Summers offers practical wisdom to help you slow down, reassess your priorities, and make the most of the life you have.
