There is no good or bad - just what you make of it

From a post by Leo at ZenHabits,

Hamlet said, ‘There is nothing either good or bad, but thinking makes it so.’
He was right. Without the human mind, things just happen, and they are not good or bad. It’s only when we apply the filter of our judgment that they become good or bad, beautiful or ugly.
A weed is only a weed when we don’t like it. Children are only naughty if we don’t like their actions. Life only sucks if you judge it as bad.
But what about truly horrible tragedies, like a plague or tsunami or the Holocaust? Surely those are bad? Sure, through the lens of the judgment we’ve been raised to make, they are terrible. But then again, remove the judgment, and then … they simply happened. Death and cruelty will probably always make us sad, but they’ve always happened and always will, whether we like them or hate them.

Full post.

So the lesson to take from this is to acknowledge that everything just is. Life happens and your interpretation of it and judgment based on that interpretation is what makes it good or bad.

I'm not suggesting to not interpret events around - that's too passive and hippy for me.  Just realize what you are doing, you might learn something about yourself when you understand why you are reacting the way you are.  And when your reaction is intentional, that's when you are in a powerful position.
