Rule #2: Aim big.
Regardless of whether a start-up is targeting a big idea or a small one, it will still require the same amount of blood, sweat and tears—so aim big! What is “big?” It is a new product or service that creates or dominates a significant market.

Rule #3: Build a network to magnify your company.
People tend to think that behind every great start-up is a single entrepreneur with a whiz-bang idea. The reality is great companies are built by a number of people with talent who are surrounded by amplifying networks. The most successful entrepreneurs bring in advisors, investors, collaborators and early customer relationships.

Rule #4: Plan for good luck and bad luck.
You should always assume you will have both good luck and bad luck with your new company. Good luck is not as simple as “it worked out.” Rather, this is when you discover a great opportunity and can quickly shift to go after it. Bad luck is what happens when your first idea doesn’t work. It doesn’t mean failure; it means you need to pursue plan B.

Rule #5: Maintain flexible persistence.
Very often entrepreneurs are given conflicting advice: “Be persistent! Stay committed to your vision!” or “Pivot on key data! Know when to change!” The challenge is to follow them both, but know which advice is most appropriate for which situation. You must know how to maintain flexible persistence.

Rule #6: Launch early enough that you are embarrassed by your first product release.
With my first startup, Socialnet.com, it took us nine months to launch the first product. That was a disastrous mistake. We wanted to have all the detailed functionality right away, including social controls to people could decide to connect or not with the people in their networks. We wanted everyone to “Ooh” and “Aaah” about how terrific the product was. We wasted a bunch of time and it put us months behind on more important problems that needed to be solved, such as how to get our product in the hands of millions of people. From that I learned, if you are not embarrassed by your first release, you’ve launched too late!

Rule #7: Aspire, but don’t drink your own Kool-Aid.
Target excellence, but be very careful about blind trust or belief in your theories. It is important to launch as early as you can in order to learn how your customers use your product or service. It is equally important to identify metrics that tell you if your aspirations and vision are on target. You should also get feedback from your network in order to iterate or pivot on the target, the product and/or the service. In other words, maintain your aspiration but always look for good perspective on how you are doing. It is very easy for creative innovators to get caught up in their own story rather than learning where they should be headed.

Rule #8: Having a great product is important but having great product distribution is more important.
I meet a lot of entrepreneurs who think the best product is the most important thing and that the best product should always win. What a lot of people fail to realize is that without great distribution, the product dies. How will you get your product in the hands of millions or hundreds of millions of people?

Rule #9: Pay close attention to culture and hires from the very beginning.
Your first hires set your culture, so make them good ones. These first people hire the next people and so on. The old wisdom was that you needed people with a decade more of experience in your start-up. The things a smart person learned a decade ago won’t help you now – you’re doing things that have never been done before, and the world and the competitive landscape are changing at hyper speeds. What you really need are people who can learn fast.

Rule #10: Rules of entrepreneurship are guidelines, not laws of nature.
Do not pay too much attention to rules set by other people. Entrepreneurs are inventors. They are successful when they make something work for the very first time. Sometimes in order to make something work, you will drive over the guardrail of one of these rules. Entrepreneurs sometimes just make new rules.
