karma

This has been bothering my lately.

I don't believe in "karma," as in, good things come to good people, or "she deserved what was coming to her."

NO.

Life is not fair.

You can't expect the bull not to eat you, simply because you're a vegetarian.

People do good things, sometimes. and sometimes, good things happen to people.

Sometimes, people do bad things. and sometimes, good things happen to those people, too.

There is no "she'll get hers, in the end."

People put too much stock in fate, luck, karma.

All you can do is:
Do your own thing.
Work hard for what makes you happy.
Keep in mind that what you want, is not necessarily what is best for others. Decide what is important to you.

You set a goal. You work hard. You work harder. You reach your goal, or you don't.
