Q: I feel confident in my skills and accomplishments, but do not seem to inspire confidence in others. I've tried to get new tasks and responsibilities, but have not been successful. What should I do?
A: Take a comprehensive look at yourself to be sure you're not sending unintended messages that are holding you back.
The inner game
First question to explore: While you're confident in your past performance, do others share your positive view?
Set aside your emotions so that you can neutrally assess the feedback you receive. What are you seeing on formal performance reviews?
Are you shown as a superstar, are you a fine midrange performer, or is there information pointing to areas of deficit? In short, can you find any clues as to why you may be overlooked for new opportunities?
Now think through a bit more why you feel you don't inspire confidence. Apart from not getting new opportunities, consider day-to-day feedback that you receive, including nonverbal reactions. Based on this, are you confident that you're accurately interpreting the situation?
For example, there are other reasons you may not have gotten new opportunities. Fair or not, if you're excellent at what you do and it's very important to your company, there may be reluctance to lose you from that role.
Now, having considered this, let's take your question at face value — you're good, but others don't see it. Take time to look at how you interact. Do you hold yourself with confidence? Speak with authority? If you appear tentative, then you will not inspire confidence. Similarly, if you appear scattered or overwhelmed with work, you won't attract additional opportunities.
