"When you want something in life, you just gotta reach out and grab it"

I hear it all the time, "I would like to travel but I cant find anyone to come with me." I always have the same response, " So go alone." While I am not suggesting you should try and move out to the Alaskan Wilderness with nothing but a sleeping bag and a pair of rubber boots, these days there a million and one ways explore the great unknown on your own.
I always knew that I wanted to study abroad in college but I couldn't find anyone that was interested in the same program as me. So I spent a Semester at Sea through a different university where I knew absolutly no one, and had four of the best months of my life. Travel is about leaving your comfort zone, there is no need to take a security blanket with you. I know that people may be scared to go it alone, I certainly was, but you would be surprised how many other travelers are in the same boat.
There are countless organizations out there devoted to sending people around the world that don't break the bank. Always been your dream to go to Asia? Why not teach in Vietnam for a summer, have your living expenses covered, and meet like minded individuals? How about getting to know new people during a two week long group safari in Uganda? If you're not interested in a structured program but still want travel buddies there are dozens of social networking sights that specialize in bringing travelers together. Couchsurfing.com, 2go.travel, and travelersfortravelers.com are all free ways to hook up with people around the world.
There are always going to be a dozen reasons why you shouldn't do something, but don't let the lack of a travel partner stop you from going anywhere. Isn't the ability to reinvent yourself part of the allure of meeting new people and going to exotic places? Do it! Give in to that wanderlust. I have never a met a single person that has traveled alone and regretted it. Be smart, be safe, and see what the world has to offer. Don't waste time waiting on anybody but yourself.
