Here's another way. This is most important. Don't allow men to be happy. Happiness is self-contained and self-sufficient. Happy men have no time and no use for you. Happy men are free men. So kill their joy in living. Take away from them what they want. Make them think that the mere thought of a personal desire is evil. Bring them to a state where saying 'I want' is no longer a natural right, but a shameful admission. Altruism is of great help in this. Unhappy men will come to you. They'll need you. They'll come for consolation, for support, for escape. Nature allows no vacuum. Empty man's soul - and the space is yours to fill.
