If the answer is NO: surrender and accept what is.
If the answer is YES: surrender to Holy Spirit and let Him inspire you what action to take.
Either way surrender brings peace of mind. Letting go of control.
Is there actually anything you can really do to change [xyz problem] right now? And be honest about it. Usually the answer is no. If you can't change it, then why have any upset about it? Why fret or worry about it? Why even get into a STORY about it? Why even try to wrestle with it, resist it, fight it, be angry about it? None of that will change it, right? So it is actually FUTILE. Why bother spending your energy doing what is completely futile? Your energy is better spent in what is productive and constructive and possible.
Otherwise you are fighting with impossibility, and you will lose.
This is somewhat the basis of the AA idea "God grant me the serenity to accept the things I cannot change, the power to change the things I can, and the wisdom to know the difference."
You need *discernment* in order to be able to tell if you can REALLY do anything at all to change matters. Discernment requires Holy Spirit's thought system, because you need to decide based on TRUE or FALSE, rather than right/wrong/good/bad/happy/sad etc. And thus you need a lot of HONESTY and willingness to admit the truth.
So discern. Is it true that you can change this? If not, then you might as well just surrender and accept it. There is much more peace to be had there. Then join with Holy Spirit for inspiration and guidance and proceed from there. Fighting an impossible fight is a complete waste of time.
I suppose this is also in line with what Eckhart Tolle suggested (and others) ... 'resist nothing' or as the Borg in Star Trek say, "resistance is futile".
