The Lazy, Vain, and Selfish User Framework

Overview

Modern internet consumers possess three inherent attributes: Lazy (no time/patience), Vain (driven by ego/habit/social standing), and Selfish (need immediate "what's in it for me"). Product design must solve for all three.

Core principle: Design for the real indifferent user, not the ideal interested user.

Design Checklist

• Zero steps to value (Lazy)
• Fits their identity/habits (Vain)
• Immediate benefit clear (Selfish)

Common Mistakes

• Assuming user is interested in your product
• Expecting users to read manuals or tutorials
• Requiring habit change without immediate reward
