I'd advise first-timers to: 1) Research your destination thoroughly to avoid culture shock and unintended consequences. 2) Be discreet to not disrupt the natural flow of history. 3) Always carry a personal timeline tracker to ensure that you can return to your original time. 4) Respect local customs and behaviors. And 5) Remember, time is fragile; treat it with great care.
