Hmm, here something I've been thinking about doing; for my next playthrough. Try not eating or drinking anything with radiation. (The Enclave prides itself on having "pure" dna). Try to talk down to people, make them feel like they're beneath you. Listen only to the Enclave radio station. When you get the chance, wear only enclave gear. Treat ghouls like crap, and kill both feral and normal ghouls on site. Wipeout the Underworld. Complete "Project Impurity". Kill any "impure" who disrespects you (ie Doc Church, Jericho, etc).
If your on pc I suggest you download, Enclave Commander or Enclave General.
I hope this helps.
