Simplicity is key. Slowing down to acknowledge the beautiful things that run in the background of our lives will maintain that simplicity. When a period of suffering ends and we have both thing we'd been living towards, and also that emergence into a freer-feeling way of life, we'll come upon this other thing: the things that threaten to drag us down into feeling miserable or bored or otherwise discontent--still dog us.
"They return at evening: they make a noise like a dog, and go round about the city." (Psalm 59:6)
Blah, blah, blah
If you've prayed at any time in your life for God to use you in a greater capacity, screens of torment will impose themselves and seek to ever darken your outlook as you continue to move through your life. If you look back, you'll see that the things that bothered you then (whenever that was) most likely don't affect you the same way. But you've grown and the (in my case) depression seeks to keep up. This doesn't mean it's your lot in life. As a child of God, you're entitled to the joys and atmosphere of Heaven here on earth. It's your (re)birthright. But as we get older in the Lord and hopefully stronger, the effort required to see and pray through the fog increases. Now, it may not be like this for everyone but if the preceding applies, God may be using you to clear out the spiritual darkness from an area--be it wide-scale or small. Until the darkness has exhausted its grip, you'll encounter this ever present feeling. Hang in there and take notice of small things.
"And the angel of the Lord appeared unto him in a flame of fire out of the midst of a bush: and he looked, and, behold, the bush burned with fire, and the bush was not consumed. And Moses said, I will now turn aside, and see this great sight, why the bush is not burnt." (Exodus 3:2-3)
Just one little particular can lead you into the time of forgetting. Of forgetting how you felt and how your day was just another of all the ones over which you thought you'd vaulted. One moment spent acknowledging God (in whatever way you choose and it can be as long as you like) can diffuse out into the ether--and clear the air. Think about it. And do it if need be.
That little moment and whatever it was that distracted you to it was most likely God trying to get your attention. Follow Him down that rabbit trail.
