To start with, you need to think about how you can live for less. You can only make world travel for a year (or longer) possible, if you are able to live for less money. Even if you are earning, you need to be able to spend less if you want to pay for flights and different excursions on your travels. If you have some expensive habits in your life, they will be hard to maintain on a round the world trip.
However there is some good news! When you are doing long-term travel, you can live quite cheaply because you will no longer need to spend a lot of money for things like a car, mortgage payments, insurance for your car, gas bills, and so on. When you think about living without these payments, it can be easier to see that you could live on less. If most of your expenses are from your lifestyle, then it is time to make some changes.
If you are planning to embrace nomad life, here are some things you can do to make it happen for you, sooner rather than later.
