I try and see things in yin & yang terms, ie shocking stuff couldn't be shocking unless there were beautiful stuff to contrast with, good couldn't exist without bad, hot without cold, etc.
Also, every action having a resulting reaction, you basically just make the things you oppose stronger through the act of opposing them.
Just think of the tremendously successful "war on drugs", lol.
Stupidity is clinging to the same mistakes but expecting different outcomes, what ?
If by contrast you accept what is as being an intrinsic part of a bipolar world, just formulate what you want but then let go of all fears of not getting it, all manner of good things start coming to you, think of going to a bar to meet girls, if you're desperate and afraid of rejection it won't work will it, if on the other hand you go in with a carefree, positive attitude, and couldn't care less if it's the blonde or the brunette, you'll have fun.
But accepting that life has a dark and a light half doesn't mean that one shouldn't have compassion, obviously.
