It is the dream that many of us have. But I really wouldn’t bother taking over the world if I were you.. The chances are it would be quite a lot of work and no-one seems to have managed it yet. More importantly, you’ll never get a moment to yourself ever again and if you want to get anything practical done you’ll have seriously compromise at least a few of your most dearly held principles along the way. You could never please everyone and sooner or later you would end up transmogrifying into someone the old idealistic you would hate.
Mind you, you’d get to eat a lot more fish eggs.
