How can a startup use the principles of the enterprising investor to generate sustainable returns?

The principles of the enterprising investor can be applied in traditional sectors like manufacturing or retail by investing time and effort into researching these sectors thoroughly. This could involve understanding the market trends, financial health, and competitive landscape of companies within these sectors. The goal is not to take more risks, but to make informed decisions based on comprehensive research, thereby considering the investment as a full-time business. It's about reducing risk and generating sustainable returns over the long run.

Warren Buffett is a prime example of a successful enterprising investor who has implemented the practices outlined in 'The Intelligent Investor'. He was a student of Benjamin Graham, the author of the book, and has consistently applied the principles of value investing throughout his career. Another example is Charlie Munger, Buffett's long-time business partner at Berkshire Hathaway, who also follows the principles of the book. Both investors have achieved remarkable success over the long term.
