The 80/20 Principle: Leverage Thinking for One-Person Companies

There's a book repeatedly recommended in indie developer circles called "80/20 Sales and Marketing" by Perry Marshall. The core idea sounds simple: 20% of effort produces 80% of results. But when you truly understand the deeper meaning of this principle, your way of working will fundamentally change.

Perry Marshall's background is as an electrical engineer who later switched to Google AdWords consulting and wrote what's considered the PPC industry bible "Ultimate Guide to Google AdWords". He brought engineer analytical thinking to marketing and discovered an astonishing fact: 80/20 isn't just a rule of thumb-it's a power law distribution in nature, working in every corner of your business.
