Everyone wants to be the runner of the world. Because running the world is awesome. But first, you'll need some other awesome things to rule the world.
Step 1: Building an Awesome Army.
Not everyone is gonna want you to take over the world, so you'll need an army. You can make one from robots, aliens, and (although boring) humans. But humans need food, while robots can run off the sun, and aliens eat humans for substanince (but your not human, your pure awesomeness in the form of a human). Humans are also REALLY unreliable, so I'd try and get one of the first two choices.
Step 2: Making Everyone Do What You Want.
Having a huge awesome army isn't enough though. Humans tend to be "brave", and seem to fight way to hard. So, your gonna have to have some sort of threat that would ruin their world, but not really affect you. Something like a death ray, a whole bunch of poison, a sun blocker, or a weird virus which could be released upon everyone. Be creative!
Step 3: Enslaving Everyone.
Well, now you've got your threat to society, and an army to be your eyes, ears, and beating sticks (Ugly sticks to all you english people). Everyone should pretty much do what you want, and if not, kill them. Remember, when in doubt, shoot them in the head. Or get one of your army men to eat them. Whichever is more convenient. But don't forget, in order to instill fear, people have to live. Give everyone a required amount of child birth mark, and some food every now and then. Living slaves are commandable ones!
Step 4: Next Step, MIND CONTROL!
Now that everyone is doing what you say, you need a more reliable source of awesomeness powers of control. You need to force them to do things. Remember, a man chooses, a slave obeys. And really, the mass people who fear you are men choosing to not get shot in the head.
So, get a group of scientist slaves to teach you everything about the mind, body, and science. Now, a true ruler would have found the error in that sentence. "But you should NEVER trust slaves!", is what one of them would be saying. And that's true. Get one of your robots/aliens/demented humans to learn everything there is about human mind control, and then get them to teach it to you. Robots and aliens will do it, and you wont have to fear that they will control you, because the human race is so small compared to theirs, it wouldn't be worth taking over. Humans though, I would be leary of. Them and their stupid reproductive systems.
Step 5: What Do You Do With This World?
Well, whatever you want! Force people to be your lover, make people give you what you want! Make inequality awesome! Its your world, do with it what you want! Remember, this all started from you being more awesome than awesomeness itself! Robots are awesome. I would check out a few tutorials on them on here. Could come in handy someday.
