I think to blame it on the system is quite unfair.
Maybe this analogy might help:
Ask 10 people to cook the same packet of maggi mee and most of
them will cook it differently.
Some will add an egg (or 2), some will add vegetables and some
will add ham/bacon.
Others may even add some other ingredients.
Some people may put in more water, while others less.
Some might use the entire packet of seasoning, others only
half.
Some people may use a bigger flame, some may prefer a small
one.
In the end, most will end up with a uniquely different bowl
of mee even when they started out with the same packet.
Of cos we can't avoid having some people who'll just cook the
standard way and not add anything.
But in the end, if ur bowl of mee is plain and mundane, u can't
blame anyone.
Afterall, u are the cook.
Hope u get my point. :P
