Never let the nervousness of taking a final make your worst fear come true. Example: When driving to school, you may think: "What would happen if I accidentally locked my keys in the car?" and then quickly forget about it. Until the very last day of school, the very last final. You have the fear again, but as you stepped out and hastily close your locked door, you stare into your window to see the keys glimmering and laughing at your failure. Don't let this failure bleed into your final!
