When you're about to embark on a fun-filled trip, the first thing you do is pack your luggage, but it's also a headache. If you're having trouble packing your luggage, you could mess up your entire trip.1. Wait until the last minute to pack your suitcaseWaiting to pack your suitcase at the last minute is a big mistake because time is so rush and you have so much to pack that you are likely to miss things or even start packing your suitcase properly. Pack your suitcase ahead of time, you're more likely to remember everything, and you'll save yourself a lot of unnecessary stress.2. You are packing everythingPacking is a process of making choices, and you may want to bring everything with you. But what you need to know is that the things you can hold in your suitcase are limited, you need to simplify your items as much as possible, especially some items that are not necessary, there is no need to carry them at all. If your suitcase is overpacked, you'll risk paying a fortune to bring your suitcase on the plane, as you may pay some serious fines at check-in.3. You didn’t pack your toiletries in a resealable bagWhen you open your suitcase and find your suitcase full of body wash, that's going to be a pretty scary thing. So remember to pack any liquid-filled items into a secure, airtight bag to avoid cleaning up other items.4. You bought a cheap suitcaseImagine when you're in a hurry to travel, you've packed everything you need, then struggle to zip your suitcase and drag it downstairs, ready to go. Just when you thought everything was going well, your suitcase suddenly exploded and all your stuff flew out. What a terrible thing. This is more likely to happen in a cheap suitcase that can't handle your gear. If you buy quality luggage, it will last you years and save you from an embarrassing hall blast.、5. You didn't check the weather reportFor your trip, you deliberately selected a sexy suspender skirt at the store, but you didn't check the weather forecast, and when you arrived at the destination, you found out that the local weather was so cold that your skirt could not be worn at all. So be sure to check the weather forecast before packing your suitcase. Keep in mind that higher-altitude destinations can be colder but sunny (so you'll need long sleeves, a hat, and sunscreen), and slick rain gear can be as cute as the lightest jumpsuit.
