A good example of both on one pair of legs was Winston Churchill. He was self-motivated - a variation of self-directed - in his political career.
The only thing that stopped him being outright self-centred was his 'Darling Clementine'.
Another example was Adolf Hitler - and Mussolini probably too, along with Joseph Djugashvili, alias Stalin ('Man of steel').
At what level does 'self-motivated' become 'self-centred' and will the culprits take one step forward? All three would have told you they 'did it for their country', one being in the end a suicide, another shot and strung up upside down on a butcher's hook and the third died in bed. Churchill died in bed, too. He'd always been at the forefront, as an officer and then journalist in the Boer War, captured, escaped, became a politician and rose to First Sea Lord in WWI. Then the Wilderness Years - after 'crossing the floor', leaving the Tories to join the Liberals - before WWII saw him raised to PM after having been First Sea Lord again. He was back in the 'dumps' again after the 1945 General Election - but not for long. The Labour Party lost the next election and Churchill was back in the driving seat until retiring in the mid-50's to let his former Foreign Secretary Anthony Eden take the reins... Churchill was given a state funeral in 1965, gun carriage and all, eulogies and so on.
He had a big ego, that's for certain. Nobody could pull that one off without real political weight, determination, you know. He was nearly out on his ears twice during WWII due to lack of confidence but bounced back and with Monty's victory at El Alamein in November 1941 he was 'on a roller'.
However, memories in the Trade Union movement were long. He'd rattled their cages in the early years, especially the miners. Clement Attlee, a moustachioed lawyer with a Labour Seat on this side of London became PM at a time of post-War austerity, nationalisations etc that no-one expected from a Tory government. It was a landslide for Attlee's party.
And why did Hitler and Mussolini find themselves on the losing side? Over-confidence and not good listeners. A mark of being self-centred, wouldn't you say?
