Clones might be perfect, but people are intriguing. We’re intriguing because we’re not all the same. We don’t look alike. We don’t act in unison. And we have different strengths—and weaknesses.

There also isn’t “one” entrepreneur:

“The thing I love most about entrepreneurship is that we come in all shapes and sizes. Some of us want to build the next Google. Others want nothing to do with that commitment and would much rather own home-based, lifestyle-friendly, online-marketing businesses. Then, in between, there are the rest of us.”

In Entrepreneurial DNA, Joe Abraham posits that the person who is suited to try and build the next Google isn’t the same person who should be opening a consultancy. The first part of the book has several examples that illustrate that what people want to do may not always be what they’re best suited to do. This doesn’t mean they’re not suited for entrepreneurship–just that they’re focused on the wrong business and/or not playing to their strengths.

Abraham identifies four entrepreneurial DNAs—

• The Builder (think Donald Trump)
• The Opportunist (think jumping into deals, flipping houses)
• The Specialist (think doctor, lawyer, writer, baker)
• The Innovator (think scientist, inventor)

—and provides an assessment tool to help you identify your entrepreneurial DNA profile (Mine is Specialist-Builder). Much of the book is then devoted to a description of each DNA type followed by seven business optimization strategies for each. They’re all things you might want to consider doing based on your business strengths and weaknesses. There are also exercises for putting what you’ve learned into action.

Entrepreneurial DNA is, at its heart, a workbook—and a very useful one at that. Unless you have everything figured out, it’s worth diving in and putting Abraham’s recommendations to work.
