AT SOME POINT in every successful business career, a discernible change in personality and behaviour must take place. It is not a question of Jekyll and Hyde or Clark Kent to Superman, just that the time inevitably arrives when the approach and outlook appropriate for taking the first few steps on the corporate ladder will no longer do. A sales director cannot think and act like a sales manager, nor a vice-president of finance like a compliance officer. So, anyone aiming to rise through the ranks must also be ready to undertake the steady self-transformation that will allow them to cross the invisible, but certainly not arbitrary, line that exists in every organisation.
