Karma is like your destiny.
Right now, it's your karma to be reading this sentence. Karma is
much like a continuum of everyone's actions. If you were to punch
The Panic Bomber in the face maliciously, that punch would come
back to haunt you. You might get sick, or get hit in the face
with a book-bag. But if you were to give The Panic Bomber a
C-Note generously, you might find a diamond ring, or get the very
last copy of 'Peter Parker: Spider-man' on the rack. The balance
of the world's karma lies in the 'give and take factor' of its
good and bad actions.
Right now you're thinking
"Wow, all I've got to do is be a good little Atom-Atron
Droid and the world is mine! Bwua ha ha
" Sometimes
even malicious mentality- like plotting to overrun the world-
will result in unfortunate incidents. Just as thinking "I
would volunteer, but my legs are broken." would land you a
free soda from the 'Ye-Old Vending Machine'.
Good-luck isn't the result of
donating money to charities and helping crazy old people cross
the street. The results for those actions are good-fortune. This
of course goes vica versa for bad-luck. Luck is generally an
undeserved or constantly occurring fortune. You could be saving
kittens from trees all day, but if you have extremely bad-luck
it's likely you'll break your leg. A person with extremely good
luck could be the laziest moocher in the universe but still find
a twenty-dollar bill in the parking lot. If you have good or bad
luck, it doesn't really matter what you do; karma's effect on you
is severely diminished and sometimes non-existent.

Good Luck - Kicking the neighbor's dog and consequently seeing
that your stocks went up a quarter of a million dollars.

your cd-player on 'The Best of James Dean'.
