People have an overwhelming desire to believe in something. Become the focal point of such desire by offering them a cause, a new faith to follow. Keep your words but full of promise. Emphasize enthusiasm over rationality and clear thinking. Give your new disciples rituals to perform, ask them to make sacrifices on your behalf. In the absence of organized religion and grand causes, your new belief system will bring you untold power.
In searching, as you must, for the methods that will gain you the most power for the least effort, you will find the creation of a cultlike following one of the most effective. Having a large following opens up all sorts of possibilities for deception. Not only will your followers worship you, but they will also defend you from your enemies and will voluntarily take on the work of enticing others to join your fledgling cult. The Indian mystic Osho had applied this rule to solely put a foundation to the Rajneesh movement which expanded to the US.
This kind of power will lift you to another realm: You will no longer have to struggle or use subterfuge to enforce your will. You are adored and can do no wrong.
