Buffet's Strategy for High Returns with small capital

Warren Buffett would focus on researching small companies in detail, finding undervalued securities, and being passionate about the subject rather than just the money. By thoroughly studying these companies, like reading through Moody's manuals or similar publications, one can uncover hidden opportunities. Buffett emphasizes the importance of being deeply interested in the field, similar to how biologists or chess players are devoted to their areas. Finding what excites the brain and delving into it intensively is key to achieving high returns, even with a limited investment amount.
