Hi Raj, For traveling the world, you could start by first saving. For that you can start FD's, RD's and invest in mutual funds(if your goal is long term to travel the World). Once you have saved enough money or taken a personal loan, you can either take a 1 year sabatical from your day job or leave it to travel full time. You can start searching cheap flights ans cheap accommodation like couch surfing or travelers hostels. On road, you can do hitch-hiking to get to places and do free activites like (hiking, trekking, cliff jumping, swimming in ponds, camping).
Hope you had a great journey, please do share your experience with us, so that we can know better about places, and plan accordingly while we travel next to that city.....keep exploring
