February 23, 2017 3 Mistakes to Avoid When You’re Challenging the Status Quo You have a great idea that will improve operations, but it goes against the way things are done. Now the challenge is to break through the bureaucracy to get your idea implemented. When you’re taking the role of rebel at work, there are a few pitfalls to avoid: Going solo.  It’s tempting to think you can do it all on your own. But you can’t. Temper your ego and collaborate with others to advance your idea. Bringing in fresh perspectives will only help. Flunking the pitch.  When you’re ready to share the idea, keep your pitch short — no more than 15 minutes — and leave lots of time for discussion and questions. Engagement is the first step to buy-in. Giving up too soon.  Set small goals and appreciate the small wins along the way. When you hit a setback, reflect on your positive progress to help you stay the course. Copy right by  Harvard Business

February 22, 2017 Build Your Own Personal Board of Directors If you’re looking to rise through your organization’s ranks, but aren’t sure how, consider creating a personal board of directors. This informal group comprises six to eight people who can help with your professional development.  There are three types of people you should include.  First, you need fans — people who support you and will deliver tough feedback with kindness and good intent.  Second, recruit potential sponsors — senior leaders who can advocate for you when it’s time for a promotion.  Third, include at least one critic. These people may be the toughest to approach, but they can be the most valuable.  Look for people who have deep-seated perceptions of you and are likely to block you from advancing. If you enlist their help, you may be able to shift the relationship into a positive one and use their criticism to grow. copy right by  Harvard Business
