After the Oprah era of over-sharing, finally professionals are putting the pieces together. A big finding is that talking, at least too much, can be taken as a sign of a lack of confidence. Sure, it's useful and recommended to hash out an idea or plan with one or two colleagues. But, beyond that, reaching out can get us labeled negatively.
That happened to me when I approached just one other professional to sort out a problem with a client. I ran by her what had happened and what I had done.
"You need more confidence. If you had it you wouldn't be here seeking validation for what you did. In this situation you won but you don't know it."
That's what she said to me. I got it. Successful people play their cards closer to their vest. They do the analysis in their heads. They trust those inner processes.
