Most people dream of traveling the world, but unfortunately, never get around to achieving their dream due to life responsibilities and a fear of the unknown.
Although you might want some flexibility rather than sticking to a strict travel schedule, it does help to have a route for your travels planned out, even if that is simply plane tickets to and from your home country.
Although you want to retain the excitement of discovery, it is important that you carry out some research into your destinations to ensure that you remain safe and do not come across any nasty legal surprises at the airport.
Additionally, research any safety advice for many countries and cities you plan on visiting, such as areas to avoid at night and scams that target tourists.
