Make physically perfect yet completely obedient clones of myself, and y'know progress in a natural order from there.
The natural order from there obviously being have my clones integrate themselves in different societies across the world, take up positions of influence and mate with women everywhere.
All the while, through the power of willpower, science and the fountain of youth (that I will have already found 3.792 years before I implement this plan.) I remain immortal.
I wait for my genetic line to be the dominant one, and then I fire a nuke at the moon, and then the world will bend to my will.
Then through the hypnotic power of Caribbean dance, the populace of the world bends to my will.
Also there will be laser radioactive zombie cyborg sea cows, I mean obviously there will be laser radioactive zombie cyborg sea cows, that's just take over the world 101 right there.
