The days when you locked and loaded your career in school, and then blasted away down that same narrow path the rest of your life, are gone, never to return. Career survival today requires thinking and acting like an entrepreneur starting a business, staying nimble and resilient, willing to pivot, and supersensitive to the market realities of supply and demand.

Over the years I have spent mentoring entrepreneurs and startups, I often notice the similarities between successful professionals managing their careers and successful entrepreneurs building a business. Reid Hoffman, cofounder of LinkedIn, helped me crystallize these similarities with his new bestseller “The Start-up of You.” Here are key survival skills for both lifestyles:

1. Adopt the mindset of a permanent beta. “Finished” ought to be an F-word for all of us. We are all works in progress. Each day presents an opportunity to learn more, do more, be more, and grow more in our lives and careers. Keeping your career in permanent beta forces you to acknowledge that you have bugs, and intend to improve yourself.
2. Regularly assess and refine your competitive advantage. Your competitive advantage is the interplay of three different, ever-changing forces – your assets, aspirations and values, and the market realities of supply and demand. Smart professionals constantly assess the market, and strengthen and diversify skills.
3. Plan to pivot as you learn. Change is the only constant in this world, and every change is an opportunity to learn. Plan to adapt, and start it every day on the side. Don’t wait for something to fail before you learn, or before you consider a change or pivot. The best pivots are to take advantage of an upside, rather than avoid a downside.
4. Build and use your network. World-class professionals don’t try to take on the world alone. People playing a solo game will always lose out to a team. Successful entrepreneurs are ones who put together the best teams. Build your network with people smarter than you. With effective networking, who you know is what you know.
5. Pursue breakout opportunities. Success begins with opportunities, but these mean nothing unless you execute on them. Others taking breakout opportunities can be dismissed as lucky, but more often it’s the result of their work to be at the right place at the right time, with the right mindset. Be curious, confident, and willing to learn.
6. Take intelligent risks. We are all risk takers. But we are not all equally intelligent about how we do it. In a changing world, minimizing risk is one of the riskiest things you can do. The most intelligent risks are those where the potential downside is limited, but the potential upside is virtually unlimited. Those are the risks every business jumps to take.
7. Maintain that sense of urgency. Entrepreneurs know that in business, change overtakes the best of big companies, and even startups have to maintain a sense of urgency to stay ahead of the curve. For every professional, opportunities come and go at an astonishing speed, so only a continuing sense of urgency will keep you alert.

In addition to you and the network around you, there is a broader environment that shapes your career potential. It’s the local culture and society around you. So think carefully about where you choose to live and work, or where you choose to start a business. Your maximum potential may be in another place in the global environment, or as a volunteer versus an employee role.

In the bigger picture, I’m convinced that we were all born as entrepreneurs, with the instincts listed above to survive, grow, and prosper. How many of these career survival instincts have you used lately to deal with the changes we all see?
