Learn to Handle People
Apart from the famous tourist places, foreigners attract attention wherever they go. If you decide to travel deeper in India, people will be interested in talking with you and saying hello. While most of these people bear friendly intentions, you might find yourself caught up in awkward situations often, dealing with warm invitations that your itinerary might not allow you to accept. Sometimes, however, the people may not have a friendly, but a business motive in befriending you. There is a risk of getting swindled at tourist places by the hawkers selling cheap articles at unreasonable prices. So, it is best to say no with a smile and keep to yourself.
However, you may occasionally meet someone who will not be too intruding but at the same time knowledgeable and willing to offer you invaluable guidance. You would want to soak in information from them. How to travel in India is about how apt you are at making right friends. Also, learn to take care of your belongings. Don't be surprised if you leave you camera unattended at a tourist destination even for a minute and it disappears.
