Consistency

This week I've been learning that life is completely inconsistent. Yes, there are things that happen consistently every day, such as the sun rising and setting, school being in session, church happening, everyday miracles. But people are inconsistent. Ideas are inconsistent. Life is inconsistent. It's hard for me to accept this- I get an idea of how people are in my head, and when they don't end up like that in real life I get disappointed. Daydreaming is a bad thing for me to do. I mix the reality with the dream, and when reality isn't as good as the dream, things get ugly.
I'm not really sure what to do about it. Do I just stop having expectations? But then again, expectations are what push people, and myself, to get better. So maybe I'll just lower them. But some of them are already too low. I'm not sure what to make of things. But hopefully with some prayer, I can get through this time of disappointment brought on by inconsistency.
