There's an expression that goes something like:
Lions don't lose sleep over the affairs of sheep.
I like it.
I really like it.
I don't think it's an arrogant or self-righteous idea, but it could easily turn into one. Rather, to me (if I can be so bold as consider myself a lion) it's a reminder to not lose sleep over things that just aren't important. That argument at work? Most likely not that important. Dinner was late? Not important. House is on fire? Maybe you should take care of that.
Most of the things in my life I have little control over. I'm growing in learning and growing here, and caring less about those things I cannot control. I can control my words (most of the time) and my actions (most of the time) but I can't control you. I can't control your opinion of me or what I have to say.
The idea of not being able to find rest because I'm preoccupied with someone else's opinion or something else I have ZERO control over is almost comical now.
I like to sleep.
I'm not going to give it away for things that don't matter.
