Being away from home means if you forgot something then you have to buy new or go without. All you need to do to ensure that your trip is successful is to plan and be prepared.
When traveling you will need to pack light, but make sure you pack everything you need. This can be complicated, but is necessary.
Pack lightweight clothing that will dry quickly and pack sparingly. You will need only about 3 outfits no matter how long you are staying. You can wash them and dry them at night. Take a fleece jacket, boots, sandals and tennis shoes and some type of head covering. Depending on where you travel this may simply be a ball cap, but if you are female and going to the Middle East you will need a proper head garment. Also don't forget to pack a clothesline.
You will also need a sleeping bag, first aid kit, plastic place setting with a plate, bowl, fork and spoon and two towels. It is also important to pack a water bottle and water purification kit.
Don't bring guide books. Try to copy any information you need. Single pages weigh much less than a whole book. Also leave valuables at home. These will make you more prone to thieves.
Always keep in mind any airline policies as they tend to be rather strict these days. You can always buy something once you reach your destination if you can not take it on the plane.
The whole point is to pack light because you have to carry it all around with you. Only pack what you need and what would not make sense to buy once you get to your destination.
