It alright to travel alone. It will be an adventure and don't let fear
get in your way. Its a test of independence and its all about being a
smart traveller. First of all, you secure everything, always remember to
check and recheck your valuables and the like. Don't easily trust
anyone you do not know but do not be rude, be simple and vigilant. Also
be thrifty and explore, after all, it is what traveling alone is all
about, the exploration. If you are a girl, never mention that you are
traveling alone or you are alone and do not disclose your last name to a
total stranger the least. It is also great to know the location of your
embassy in a foreign land so that when you are in trouble you know
where to possibly go. Its also good to tell someone where you are so
that if ever you can't be found or what, someone knows where you might
have gone. Good luck!
