Jeff Bezos says Amazon's rise can be traced to four simple rules. In a 2009 video recorded after Amazon announced its purchase of Zappos, the founder distilled the company's playbook to four particular principles that guide its success.
Bezos’ four principles were, "Obsess over your customers," "Invent on their behalf," "Think long term," and "It's always Day 1." The principles carried a business that grew from two people packing books in a garage, with Bezos labeling packages and driving them to the post office while his then-wife, MacKenzie Scott, sealed boxes, into a company valued at around $2.3 trillion today.
