Basic Business Library

There's a good series of books by Barron's under the "Business Review Books" label. They cover major areas of business management, like "Marketing", "Finance", "Accounting", and so on.

Robert Kiyosaky's "Rich Dad, Poor Dad" series explains fundamentals of personal finance in an entertaining way, though "The Total Money Makeover" by David Ramsay is more practical.

Sales is probably the most needed skill in business. Even in corporate environments, employees have to continually sell themselves. Zig Ziglar has written many titles on this subject. Pick any one; he basically re-wrote the same book many times.

On personal things, I can see the merit in the "Dress for Success" thing. It is important. I like behavior skills better. (Doesn't mean I'm better, just that I recognize their importance.) Try "Talk to Win" by Lillian Glass.

Robert Kiyosaky make a good point about using network marketing as a practical means to work on sales skills. Here's a good, practical book on this: "Your First Year in Network Marketing" by Mark Yarnell and Rene Reid Yarnell.

If you work in accounting like I do, be sure to keep an annual GAAP Guide. I use Wiley's.
