No matter what your status is or how well
you're doing in life or anything like that - there are three things
you'll always be running after: money (or wealth, power, control etc),
sex (or romance, love), and happiness.
These are things you'll never be able to
fully achieve - you can achieve it for a moment, but then after some
little time you'll already be looking for a better one: the next
achievement. And you'll be bored with your current situation. And this
will happen all the time. With anything related to those three: power,
romance and happiness.*
So here comes the big boom: why do anything related to those three, if after you accomplish your goal you'll not be satisfied?
*In the end they are all the same: the
search for happiness. Which in turn is something else: the search for
absence of pain. So, what you're really looking for is the absence of
pain. Why though?
