If you're like me, then you
Now, I think Jesus knew that there would be people like me in this world- planners - because He flat out says "In his heart a man plans his course but the LORD determines his steps (Proverbs 16:9). The older I get, the more I realize that this couldn't be more true.
While I do think it's important to keep your standards high ("Keep your heels, head and standards high, ladies") I think that the line you can't cross is found at the point where you're making yourself miserable because little details don't work out. God has it all under control and He knows what He's doing! Don't let those hard-headed expectations steal your joy!
