One of the biggest lessons when it comes to working with friends and family is to have the confidence to fire your mother-in-law if need be. The way to keep issues with loved ones out of the boardroom is to create what I call a start-up prenup, a document that puts the rights and responsibilities of each partner on paper. It's OK to start a business with those you love, but make sure you have a plan if the love goes away. But too often I've seen the dreadful alternative. My advice is formalize your partnership agreement.

Agile leaders encourage their teams to adjust and experiment constantly. In today's age of oversharing, the best leaders also have to be more open and accessible. To be effective, you also have to be aware of how others perceive you and cop to your flaws every now and then. One of the lesson to successful leadership may be quite challenging but very important. Expose yourself. Allow yourself to be vulnerable - less super and more human. These "Leadership 3.0" practices, as I call them, are critical to being an effective manager when you're getting started in today's world.

In my experience, some of the biggest obstacles to becoming a successful entrepreneur aren't financial or structural - they are internal and psychological. It's important for dreamers to believe in themselves and their ideas, to fend off the skeptics and find others who will share in their dreams. Once you understand that being called "crazy" is a compliment, you realize that you can get beyond other people's opinions and zig when others zag.

When Edison first started out with his "crazy" idea for the light bulb, skeptics were unmoved. They called Thomas Edison a con man and taunted him to prove his bulb could really work. Despite the naysayers, Edison pushed on, demonstrating the importance of sticking with his "crazy" idea which would go on to turn him into one of the world's most well-known entrepreneurs. The key here is to fan the foolish fire no matter what!

The most important lesson of all: Go home. Make time for the ones you love. The easiest thing to think about living like an entrepreneur is that these skills apply to only one part of your life: your job. That's a mistake. In the same way that entrepreneurs are redefining many of the traditional rules of the workplace, they're also helping to break down one of the most stubborn boundaries of all, the one between work and family. While it's popular to say you can have either a successful career or a meaningful personal life, I'd like to suggest you can aim for both.

One of the key skills you'll need to bring change to the world will really test your creativity, as well as your sanity, your patience, and your resolve. It has to do with how to take your dream and make it as real as possible. It doesn't really matter what your dream is, "going big" means doing it to the utmost. To do that, you need one thing: other dreamers to share your dream. If you learn to make your dream a team effort, you'll find the key to growing big.

If you're not called crazy when you launch something new, it means you're not thinking BIG enough.
