You are never 100% ready in each and every situation. There is always room for improvement, even in situations where you may feel that there isn’t. Tackle your meetings and tasks from different perspectives, and don’t be too confident. You don’t want to come off as arrogant. Don’t be too nestled into your plans; allow room for change. Plan for the unexpected, and be ready for anything. You never know when someone will throw you a curveball.
