This is not a questions about your desire and whether you want it or not. You would like to understand triggering mechanism behind those swings and why sometimes you'd go for it and the other time you'd not. Right?

I won't present you with a technique for they almost always lead you astray from understanding the nature of what you're trying to apply the technique on anyway. That's why I deem them all useless, for if you know what you're dealing with, you'll always figure out the most suitable way to go about it in any situation rather than having a step by step manual which often times is not adaptable.

There are at least 2 major things at play here. 1 - cause and consequence, 2 - change.

It is important to understand/analyze the situation you're at right at the moment and find out whether you are still or in motion. Not so much physically as decision making wise.

I will try to explain the very subtle difference between being still and caught up in a domino like effect of cause and consequence where the consequence becomes another cause perpetuating another consequence. If you would imagine a vast field and there were signs scattered all over it, saying go right, go left, go forward etc. Being in the domino effect is like following those signs blindly. Being still, is stopping at each sign and making a brand new decision sometimes contradictory to what is the sign at the place you are at suggesting.

Understand that paradigm of cause and consequence will be always present. In both scenarios. But when being still (and I'm referring to having a quiet mind and being unattached from everything here) you will not be prisoner to current circumstances. In other words, the every day situations and experiences you encounter throughout the day.

To present more of an real life example, if you enter a room full of people and everyone starts smiling at you, your immediate response would most probably be to start smiling too. You don't say: hold on a moment, why should I be smiling now?. You give in to the circumstance and follow the signs blindly.

You are either consciously evaluating the situations, thus you are finding possible triggers, therefore you are able to avoid them and their consequences, or your going "with the flow". Conscious evaluation gives you more options and more freedom. And that can be done only when you judgement is not clouded and your sight blinded. Which happens only when you're still and look at everything through eyes that know no attachment.

Now, as far as it goes for - change. Everything is constantly changing. These changes big and subtle are triggering multitude of causes and consequences that is happening every single moment all around you, most of which however go unnoticed. As you are closed to some and open to others. Based on your limitations...or your beliefs, if you will.

And through any situation you analyze you will learn more about yourself. Never mind what's going on all around, because ultimately what you want is to expand circle of influence about your own life.

I'd like to use parable that when you were born, you were handed over an alien ship. As you pressed each button you learned to navigate the ship, communicate with other ships, get yourself over to many places. But there is so much more that you don't know. The ship has many programs which you have no idea how to control. Like your battle mechanism of immune system. Shields go up and turrets fire when there is a danger, but you have no clue how to do it manually. On other planes, like emotional, spiritual and such you may be caught in jumping from place to place through hyperspace, and unless you learn to control hyperspace navigation one moment you'll be happy, the very next moment you'll be crying. That's why it's viable to stop the ship for a moment and find out what each button really does. Eventually, if you would gain full conscious control of the ship, infinite possibilities open up. And the universe is your for taking.

The point is, you phrase your question incorrectly. In sense, that you are drawing your attention away from yourself and towards the circumstances around you. Because there are no daily swings, there is only your inability to press the correct buttons to compensate for circumstances around you.

So the question really is, how do I learn to fly the ship instead of how do I stop meteors flying to it and hitting it.

And hopefully, you've learned a bit of that through my incomplete explanation above. And while there is a lot more to talk about, I assume that it couldn't be digested at once anyway.
