Change isn’t easy. Most of us hang on way longer than is emotionally healthy, or in the case of our professional development, remain stagnant in our career longer than is strategically wise.We’re living in a new world of business and the old rules no longer apply. The start of a new year is always a great time to reassess where you are today, review and determine your potential, and explore future possibilities. With this in mind, consider the following six reasons to give yourself permission to shake things up in your career.Reinvent Reason #1: You’re not as quick as you once were in responding to opportunities.We can all get stale and complacent in our careers. But you don’t have to change jobs to reinvigorate your career; you just need to identify three things that you can do differently about the job you have today. Give yourself a timeline–30 days, 60 days, or 90 days–and reward yourself when you meet your rejuvenation goals.Reinvent Reason #2: You ignore inflection points (or don’t know what to look for).Inflection points usher in transformative change for individuals, organizations, and businesses. Increase your opportunities for leveraging this transformative power by proactively managing inflection points in front of the curve, or before the curve changes sign from either a positive, upward curvature to a negative, downward one. Allow an inflection point to pass you by and you risk falling behind and struggling to close the “curvature gap”. You’re better off learning how to recognize early signals that clearly put you ahead of the game.Reinvent Reason #3: You’re in denial about missed opportunities.When was the last time you looked over your shoulder to see what you didn’t take advantage of, but had the opportunity to do so? Maybe you weren’t feeling at your best–too tired to fully engage during a networking event, hungry because you skipped lunch, or irritable because your last meeting was a clash of politics and personalities. Next time, monitor and adjust your emotional temperature and watch your missed opportunities drop.Reinvent Reason #4: You think succession strategies are only for executives.Managing your career like a business means that you develop a succession strategy designed to build your credibility for the long haul and establish a legacy over time. A good rule of thumb is to always put together a hand-off plan before you move on, whether you’re changing positions inside the company or changing jobs. Be known for your legacy of building not burning bridges.Reinvent Reason #5: You use your global viewpoint only while on vacation.We’re all connected and inter-connected in a reinvented world, which is why it’s critical that you understand how business is done in other countries. Innovating cross-culturally and collaborating with distributed teams in virtual settings requires that you develop a comfort level for working alongside cultures different from your own.Reinvent Reason #6: You’ve been “milking” your last innovation for the last ten years.Creating ongoing value in business and in the workplace differentiates professionals operating in the new world of business from those hanging on to the old world of business. When was the last time you accomplished something truly innovative–solo or in a team setting? Go back and review #1, then get started on your next career reinvention!
