If you can afford to travel, you’re luckier than an enormous chunk of the world’s population. Be grateful that you were born in a country that’s safe and stable. Be grateful you have a passport that allows you to easily travel. Be grateful that you have your health. Be grateful you were able to get a job; that you had the ability to save up enough money to travel. Yes, you worked goddamn hard to get to this point, but you’re still unbelievably privileged. Never forget it.
Don’t forget to squeeze in some light exercise in between flights and meetings. A 30-minute walk around the airport or a simple stretching routine when you feel tired is often all that is needed to refresh. Exercising also keep the body metabolizing at the ideal rate, which means you can sleep better at night and not have to worry about possible health problems ruining the trip.
If you're going to be traveling routinely, it's worth buying duplicates of key items and leaving them in your travel bag, versus remembering to repack them after using them at home. For me, this is things like laptop and phone chargers, toothbrushes, and basic toiletries. I rarely forget these necessities since I have a travel set that's always in my suitcase or laptop bag.
Whether due to a travel delay, a never-ending meeting, or arrival in a different time zone, you're bound to end up hungry at some point with limited appealing food options. I always carry three to five energy bars of some sort for just these situations. Look for something that doesn't melt, crumble, or expire, and is well-packaged so it doesn't end up spilling in your bag. I like Kind bars, as they're still relatively tasty even when flattened and deformed after a few weeks in my laptop bag.
So, when it comes to packing personal items, it is best to keep it scant. Dark colored clothes are a plus because they hide stains well and can often be reworn. Shoes without laces are extremely convenient for getting through security. A Dopp kit or toiletry bag can be within your set of go-to’s to ensure you don’t show up to a meeting with rancid breath because you forgot toothpaste. Gather the essentials here and ensure that the rest is versatile.
