In their book, The Start Up of You, LinkedIn cofounder and chairman Reid Hoffman and author Ben Casnocha show how to accelerate your career in today’s competitive world. The key is to manage your career as if it were a start-up business: a living, breathing, growing start-up of you.

The challenge is to “invest in yourself, invest in your network, and invest in society” to give yourself a competitive advantage in today’s volatile marketplace.

Here are some the top 10 quotes that stood out to me:

1. All humans are entrepreneurs not because they should start companies but because the will to create is encoded in human DNA, and creation is the essence of entrepreneurship.
2. No matter how brilliant your mind or strategy, if you’re playing a solo game, you’ll always lose out to a team.
3. We are all risk takers. But we are not all equally intelligent about how we do it. Many people think you get career stability by minimizing all risk. But ironically, in a changing world, that’s one of the riskiest things you can do.
4. You remake yourself as you grow and as the world changes. Your identity doesn’t get found. It emerges.
5. Each day presents an opportunity to learn more, do more, be more, grow more in our lives and careers. Keeping your career in permanent beta forces you to acknowledge that you have bugs, that there’s new development to do on yourself, that you will need to adapt and evolve.
6. If you try to be the best at everything and better than everyone (that is, if you believe success means ascending one global, mega leader board), you’ll be the best at nothing and better than no one.
7. Whatever the situation, actions, not plans, generate lessons that help you test your hypotheses against reality. Actions help you discover where you want to go and how to get there.
8. A slightly less-competent person who gets along with others and contributes on a team can be better for the company than somebody who’s 100 percent competent but isn’t a team player.
9. The fastest way to change yourself is to hang out with people who are already the way you want to be.
10. Relationships are living, breathing things. Feed, nurture, and care about them: they grow. Neglect them: they die.
