It’s sometimes one of the scariest words in English language, but it’s a word you should be prepared to say when opportunities arise in your career: Yes.
   I’m not saying you should blindly accept everything that’s offered to you: it’s okay to take time when considering the pros and cons of an opportunity. (16)But, when you find yourself leaning toward "No," you owe it to yourself to be sure that you’re turning down the opportunity for a valid reason, not just out of fear.
   Consider this: Will the experience enhance your knowledge and play to your strengths? Will it introduce you to new concepts and new people? Will it require you to develop new techniques for managing your team or working with more experienced people? Embrace this challenge and get out of your comfort zone.
   When I find myself wanting to shout "No!" to an opportunity, that’s a sure sign to me that the answer should probably be "Yes. "So, I take a deep breath and analyze the situation as objectively as possible.

Before you can learn any of these things, you have to learn to say "Yes." It’s okay to acknowledge the butterflies in your stomach: however, it’s not okay to let them stifle your growth.
   (18) When you need help, reach out to people in your networks—that’s what they’re there for. Whether you need a confidence-boosting pep talk or advice about building your technical experience—your mentor, your colleagues, and your manager can help. You may not know how to do something today, but chances are you’re smart enough to find someone who can help you learn it. And once you do, don’t unfasten your seatbelt—there’s always going to be another challenge headed your way.
