09. Keep Your Foreign Cash
Firstly, you should have a proper foreign currency backing with you before embarking on a journey. And you should get that from local currency exchangers before going to the airport because the exchangers at the airport will have the rate higher than the local ones. Secondly, save a little amount of money when you start your journey. It will come in handy when you will get back from your adventure. Not spend all of it rather save a certain amount.
