PersonalMBA really is a my go-to reference because it is very comprehensive and extremely accessible online. First 5 chapters tackle the strategy behind the '5 parts of every business'
1) Value Creation 2) Marketing 3) Sales 4) Value Delivery 5) Finance
The next 6 Chapters deal with the tactics involved in executing that strategy. 6) The human mind 7) Working With Yourself 8) Working With Others 9) Understanding Systems 10) Analyzing Systems 11) Improving Systems
I've given it as a gift to other friends.
