Start Now

No doubt travelling is too expensive only if you are not committed. Plan your budget and start this moment. Stop being lazy and putting it off. The longer you wait the more far will it be. Try having all things set, from the list of things you might need in the trip to your documents and all other necessities. If someone is coming along with you to the trip, try to sort everything between yourselves related to every domain, especially monetary expenses and always stay in touch with each other before leaving for the trip.
