Excuse #2: I don't have anyone to go with

You don't need anyone to go with! I've gone on backpacking trips through Europe and South East Asia by myself and have never had a problem meeting people along the way. If you stay in hostels, you will easily meet other travelers. Money exchanges, airports, markets, and walking tours are other prime spots for making friends. If you're more interested in meeting locals, try a homestay, volunteer, or just seek out the cafes and bars where locals hangout and strike up a conversation. The best thing about traveling alone is you never have to adhere to anyone else's schedule. Instead, you can wake up when you want, see what you want, and do what you want without having to feel the need to coordinate with someone else.

Excuse #3: I'm too young/old

You are never too young or too old to travel. If you're young, why not do something abroad to help build your resume, like volunteer, study, or intern abroad. If it's a matter of your parents being worried and you want to appease them, join a tour group like Intrepid Travel or G Adventures so that you'll be with an experienced guide as well as other young travelers.

If you think you're too old, think again. There are plenty of older people out there, not just traveling, but backpacking and trekking their way around the world. In fact, just this past October, 84-year old Richard Byerley broke a new world record and became the oldest person to summit Mount Kilimanjaro. And before him, the oldest person to do this same feat was 82-year old George Solt in 2010. If you still feel skeptical, there are tour groups that cater to those in their retirement years, like Road Scholar and Grand Circle Foundation.

Excuse #4: I'm afraid to fly

According to planecrashinfo.com, the chances of you being killed on a plane flown by one of the top 25 airlines is 1 in 9.2 million. And, even if you went with an airline that is deemed to have higher accident rates than the others, the chances are still slim at 1 in 843,744. If logic still doesn't assuage your fears don't get dismayed, you can still travel. Fill up your gas tank and take a road trip, pack a bag and travel by bus from city to city, or, for something a little more luxurious, opt for a relaxing cruise.

Excuse #5: My boyfriend/girlfriend/parents don't want me to go

While it's understandable that the people who love you will miss you, they should also try to be happy that you're doing something that will make you feel fulfilled. There is so much technology available nowadays that keeping in touch is easy. Video chat on Skype, send e-mails, or keep a blog to let your loved ones follow your travels and know that you're safe.

If it's a significant other that's keeping you from traveling, ask them to come along with you. And if they can't, you still shouldn't give up going on a trip that will enrich your life. As for your parents, it's only because they are worried about you, so try to ease their minds as much as possible. Call regularly and send them photos, make it clear how responsible you plan on being, and show them blog posts and articles from other travelers who have been to the same cities. Despite the fact that I've backpacked myriad countries alone, my parents still worry, and that's something that will never change. But, these trips have helped me have experiences I never would have otherwise and have helped shape me into the person I am now.

Excuse #6: Traveling is dangerous

While I hear this one a lot, it's always amazing to me that people can put such a blanket statement on traveling. Isn't life in general dangerous? I've also heard that driving, smoking cigarettes, playing contact sports, drinking alcohol, and eating fatty foods is dangerous, but I'd say majority of the people I know do most of those things. You need to take risks in order to live a full life. Of course, you should take precautions. Walking back to your accommodation alone and drunk at 3AM in a foreign city (or even your hometown) probably isn't the best idea. But if you use your brain, you should be more than fine.

One thing I always find, too, is that people perceive other cities as being more dangerous than they often are. On a recent trip to Ghana, Africa, my friends were extremely worried for my safety. On a hike in the Volta Region I asked a local who I had befriended if he would ever come to New York to visit me. His reply? "Isn't New York one of the most dangerous cities in the world?"

Excuse #7: It'll ruin my career

Most jobs give you time off (and if they don't, maybe you should try looking for a new job), so use it. If you get two weeks take two weeks vacation, and try to plan it around holidays and weekends so you can add extra days into your trip. If you're looking to go for longer, don't look at it as the end of your employability. Traveling can help build and enhance your skills and also shows how adaptable you are as a person. You may also discover things about yourself along the way that can lead you into a job you didn't even know you wanted, like teaching abroad, travel journalism, being a tour guide, or working for a nonprofit or travel company.

Excuse #8: I have a family

Take them with you! Just ask Meg Nesterov who writes Gadling's Knocked Up Abroad, chronicling her travels with a baby. There will be challenges to traveling with a family, but with the right attitude and some planning it isn't impossible. If your kids are a little older, they will be introduced to unique cultural experiences at a young age, and you can seek out destinations that have opportunities for learning. There are also tons of hotels out there that cater to families, and many homestays and volunteer programs that will accept families with children, as well.

Excuse #9: I'm scared of being culture shocked

Even the most well-traveled individuals can experience culture shock, and it's completely normal. However, you shouldn't let the possibility of some discomfort abroad stop you from seeing a foreign land. If it's your first time traveling, start with a country or countries that are more Westernized and speak English. Once you get more comfortable with being away from home, you can start to branch out little by little. If you get to a place where you really feel uncomfortable, don't run away but instead face the obstacle head on. Realize the unique experience you're having and try new things that you never imagined you would. You can always sneak back to your hotel room and write your thoughts in a journal when you need a break.

Excuse #10: I don't know a foreign language

Obviously, you can solve this problem by traveling to destinations where they do speak your language. However, by only sticking to primarily English-speaking countries you can miss out on a lot of great cities. You'd actually be surprised how many people in non-English speaking countries can, in fact, speak at least some English. And when they can't, using hand gestures, pointing, and carrying a pen and paper to write down the names of landmarks or draw pictures can be very helpful. And just to be safe, a pocket dictionary never hurts.
