The purposes of travelling are different for different people. There are some people who travel for the sake of pleasure. The people that are heavily burdened either at their domestic front or at their offices move too far off places for relieving their worries and anxieties. The poets and writers make a trip to distant places for collection of facts for their Writings. Businessmen also visit various places to enquire as to whether there are scopes for expansion of their business. It is common for statesmen to visit other countries on a goodwill mission.
