I have only come across a handful of brilliant leaders and managers in my working career.
The ingredient these people shared was, they were intrinsically drawn to “doing the right thing”. The “right thing” for these leaders and managers wasn’t always popular. The act of choosing for them was sometimes personally agonising, but they still made those decisions.
When questioned, many leaders and managers know what “doing the right thing” is, but quite often, mysteriously, they just don’t make that decision. Thus, opportunities are lost, credibility is questioned and results are lower than expected.
