You make a plan, a plan in your head, and assume that’s how things are going to happen. They won’t.
Maybe you thought you were going to the cinema for a movie and a quiet night, but somehow you end up with a group of friends you haven’t seen in a while, drinking and chatting until the quiet hours eventually arrive.
Maybe you thought you were going to see an old friend at a certain place at a certain time, but he doesn’t show up in the three hours you wait (with others).
Maybe you really thought you were finished, but you know you’re not.
Plans change, nothing is concrete, people are unpredictable. This is not a bad thing. Life should be about the unexpected.
Maybe you should plan for the unexpected, but you’re probably planning yourself into a corner.
