- Listen for cues. Don't let them drop, and don't react to something that hasn't happened yet. Listen and react -- just like you do in real life.
- Don't make random movements. Every move you make onstage as your character should mean something. If it doesn't, don't do it.
- Write your blocking down right away. The longer you wait to write them down, the more likely you are to forget it. If you didn't take notes during rehearsal, do it right after.
