Arctic Explorer and Leadership Philosopher Earle de Blonville, FRGS, delivers Leadership lessons drawn from his personal experience of leading Australia's first Arctic expedition, to East Greenland. On this harrowing expedition, everything that could go wrong did so, sometimes more than once. The key lessons de Blonville explains here are that the future is always unknown, uncertain and impossible to be prepared for just by training based on hypotheticals. The single greatest truth revealed is that the only certainty is uncertainty, meaning that Leadership requires being ready for any circumstances, most of them unexpected. This means Leadership is a matter of personal character, flexibility, adaptiveness and courage, not of authority, status or force of personality. The leader must humbly accept that no one can ever be sure that any decisions taken under duress, in the field, are right, reliable or anything more than best guesses. Only time will reveal if they were. As today's Climate Catastrophe increases its grip on our planet, these Leadership Lessons from Hell will become more relevant and valuable.
