The 25 Sales Skills: They Don't Teach at Business School
Stephan Schiffman · 2026
🎙 Narrated by Stephan Schiffman (author-narrated)
57/100
👎 Skip It
Schiffman's numbered, no-nonsense tactics come from a genuinely deep sales-training career, and his own narration keeps it grounded and direct. The catch is the content dates to 2002, so anything about prospecting, gatekeepers, or events may feel out of step with today's digital-first sales world.
