One reason "positive thinking" is eschewed by so many self-help guru's is that it "doesn't work" for everybody.
Practically, it is so powerful that it immediately dredges up all the negatives you have stacked up to ensure that it doesn't work. It's your basic game-ender. If anyone and everyone could simply have anything they think about come true, then the world as we know it would end. Everyone could be rich, happy, successful, peaceful - you name it.
So all this work we've put into making this fascinating play-ground around us called "Reality" - all of that would be for nought. We've just been wasting our time.
And that, of course, brings us right back to why you have to first be grateful for everything you have around you - all that is happening to your right here and now. Because you put it there and you did a great job of it.
At that point you can then say, "well, let's see how we could make it better."
The last thing you want to do is keep combating all the creativeness that's happening around you. Fighting against stuff just makes it more solid. Realizing that you had something to do with whatever it is that's bugging you - that's the first step to solving it.
Yes, that's positive thinking. You start thinking positive. Even if it's just a little "Boy, I sure screwed that up." And then revel in how well you did it. Then you can start "fixing" it.
The point is that this is all creative.
Now, this line of approach also brings us to a very interesting point. The logic goes like this:
Self is basically infinite. All-compassing, etc. (Many people have equated this with God - but that's their equation.)
You are part of Self - just with your own purpose, Free Will, etc.
You are therefore possessing infinite potential.
- - - -
Go ahead and swallow that for awhile. The next step is worse.
Everything you create has infinite potential.
Whew. But it's all true, logically.
And if you don't accept this, or some other thought comes in like "he's off his rocker", or "yea, right." All those are perfectly valid thoughts. You thought them, so they must be true.
All I'm offering here is another concept of how you could be running your life. Just another option.
So have fun with this. Go on and try being infinitely positive for awhile. All that's going to happen to you is that you'll be running into your own counter-thinking and creations as you do.
