I think we can all agree that crushing your enemies, seeing them driven before you, and hearing the lamentation of their women is best in life, but what are some others?
in no particular order of bestness:
climbing a mountain before sunrise then watching the sun rise
and seeing the sun go down while laying back on the beach
watching your wife as she sleeps and thinking how beautiful she is
I can't relate but, holding your newborn child.
hearing your cat purr or seeing your dog wag it's tail because they think you're awesome.
an ice cold beer on warm/hot day.
freshly-ironed slacks warming your nuts, showered, shaved and feeling dapper.
