I like this quote “We judge ourselves by what we feel capable of doing, while others judge us by what we already have done“. – Longfellow.
I find it so true both on a professional and a personal level. Because we are often judged by others on our past track record, it is extremely difficult to explain that we have decided to change, and that we intend to change. And even more to explain what we feel capable of doing in the future if it looks vastly different from what we have done in the past.
As a personal note, the most salient occasion where I have observed this was when I was an expatriate. The home office was still judging me on the basis of what I was doing before departing a few years earlier, while of course by experience grew tremendously from the exposure (hence, a divorce to be expected with my employer).
When we face this issue, explanation is one way, but action is probably the most effective way to demonstrate commitment and that we take a new orientation seriously, based on what we believe we can achieve. It may involve some significant initiative-taking. But that’s worth it!
