When I'm super worried and stressed about everything in my life, it's usually because of ONE thing. One aspect of my life that has me seeing through a negative lens.
I wholeheartedly believe in giving it all up to God, but if we don't know what exactly we're giving up, entering back into our vicious cycles seems more likely - at least it is for me.
I propose that on days when the simplest task seems near impossible, when everyone else seems to be messing up our day, and when calm is a mere memory, we find that ONE thing.
I'm not saying that there won't be days when we will have no idea what's wrong, because there will be. There will be days when the annoyance in our hearts has nothing to do with us. There will be days when God has put a random stranger's struggles on our hearts. There will be days that just feel like bad days.*
Having said that, I do think we owe it to ourselves (and the people we're hurting, because of our bad day) to try and figure out [to some degree] what is going on. Whether it's one of the aforementioned things or ONE thing.
That one thing could be a test or an interview you didn't realise you were thinking about. It could be the loss of something (a job etc.) or someone dear to you. When we find this one thing we no longer have to pray these vague blanket prayers, but we can focus on this one thing. When we find this one thing we are able to be more intentional about the way we react to everything and everyone around us. When we find this one thing we can nip our stress and our fears in the bud.
*My opinion is that no matter what the reason is, you pray.
