Things to consider when packing:

• Will this be too heavy for me to carry? If the answer is yes, pull it all out and start again. You will need to be able to carry it.
• Is it securely locked? Even backpacks can take locks, or some airports (eg. in South America) offer a plastic seal service to make sure nobody tampers with your stuff.
• Will it hold? If you’ve bought a cheapie suitcase from Thailand make sure it won’t fall open by taping it up. Many luggage shops sell straps.
• What season/weather am I packing for? If you’re heading somewhere tropical, ditch the fluffy boots.
• Roll tightly. You will be able to fit much more in if you roll clothes up.
• Seal toiletries. Leaking shampoos are to be avoided.
• What will I be able to buy once there? Take into account that while traveling you are likely to shop. Leave room for additional items.
• What am I not allowed to pack? Most airlines have restrictions. Check their website to make sure you won’t have to chuck out anything at the airport.
• Have I packed my own luggage? Don’t let random people pack your packs and don’t offer to transport anything unless you know the person very, very well.
• Does it look like everyone else’s luggage? If the answer is yes, cover it in ribbons, stickers, anything to make it clearly yours.
• Do I really want to carry this? Look at each item long and hard, and be ruthless. Do you really want to carry the Lord of the Rings trilogy (books) around the world with you? Your pet rock?
