One travel technique that has worked very well for me takes place the day before my trip: using a pre-travel prep-and-packing checklist. I created this checklist about 15 years ago and still refine it occasionally. This list has three sections:<p>A) Preparation tasks: Like printing essential travel documents, saving a backup to my mobile phone, buying foreign currency, activating data roaming, etc.<p>B) Packing list: Mine currently has about 30 or so items, covering everything from the very basics, like toothbrush and toothpaste, to the often-overlooked, like reusable ziplock bags, microfibre cloths, etc.<p>C) Last minute checks: These are final tasks to complete just before leaving home. This includes double-checking that passports are packed, non-essential electrical appliances and lamps are switched off, balcony doors are locked, wet waste has been properly disposed of, etc.<p>By the time I step into a taxi or train to the airport, I can fully focus on the journey ahead rather than worrying about forgotten items. After all, this checklist has served me well for the past 15 years. Every item is checked off before I leave home, so as soon as I get into a taxi or train, I can relax, knowing that nothing has been forgotten.
