Master the fundamentals, hone your business instincts, and save a fortune in tuition. The consensus is clear: MBA programs are a waste of time and money. Even the elite schools offer outdated assembly-line educations about profit-and-loss statements and PowerPoint presentations. After two years poring over sanitized case studies, students are shuffled off into middle management to find out how business reallyworks. Josh Kaufman has made a business out of distilling the core principles of business and delivering them quickly and concisely to people at all stages of their careers. His blog has introduced hundreds of thousands of readers to the best business books and most powerful business concepts of all time. In The Personal MBA, he shares the essentials of sales, marketing, negotiation, strategy, and much more. True leaders aren't made by business schools-they make themselves, seeking out the knowledge, skills, and experiences they need to succeed. Read this book and in one week you will learn the principles it takes most people a lifetime to master.
For the rest it depends on what you need since they are very focused on one domain but for instance for accounting/finance: Cost Accounting by Charles Horngren, or Managerial Accounting for Managers by Eric Noreen is a must.
Strategor - English version by João Albino-Pimentel is amazing. A lot of tools to get started are there with very neat examples from the industry.
I have a few books that are great too. But if there is one to buy it could: The Personal MBA and then for each section get real education one way or another. From textbooks or anything.
As an aside, for non-programming mental models I found the Personal MBA by Josh Kaufman to be fantastic. Its title and marketing cheapen it a bit but the content is on point, extracting the best reusable patterns from graduate business education.
