Who Moved My Cheese was ok. I didn't think it was as amazing as people built it up to be. Most of what it said seemed pretty obvious. It's a quick read and probably worth the time tho.
I just ordered a bunch of books on business/management/work ethic that may be of interest to you. I'm not sure what your work situation is, but I'm a computer engineer with only about 2-3 years real work experiance. I'm trying to weigh my options and determine what direction I want to take my work/future education in so I ordered the following books hoping that they'll help me decide. I haven't read them yet, but I'll update you as i do if u want.
-Sun Tzu and the Art of Business: Six Strategic Principles for Managers
-As the Future Catches You: How Genomics & Other Forces Are Changing Your Life, Work, Health & Wealth
-The Transparency Edge: How Credibility Can Make or Break You in Business
-Rich Dad, Poor Dad: What the Rich Teach Their Kids About Money--That the Poor and Middle Class Do Not!
-The E-Myth Revisited: Why Most Small Businesses Don't Work and What to Do About It
-Execution: The Discipline of Getting Things Done
-Love It, Don't Leave It: 26 Ways to Get What You Want at Work
All of these got pretty good comments on Amazon. Hope it helps.
