What's the hardest thing to govern?

Aah! Of course you have the answers.

It could be any of the following:
a) People
b) Fetishes
c) Allergies
d) Number of greys one keeps sprouting everyday
e) Your enemies
f) Your friends
g) Your parents
h) Money of course
i) Assets (movable and immovable)
j) Pets
k) Wrinkles
l) The weather

But no...the hardest thing to govern is of course as the great Queen Elisabeth I would have us believe is, 'the heart'.

Aww well...
