You don't have to know the HOW only the WHAT. When you begin to focus on every single thing that you desire in great detail in every area of your life, as if you were living that moment now the Universe will bring all cooperative components together in divine timing to make your dream a reality.
You ought to be dreaming big. But wait a second, how can/will you know that your dream is big enough? It's so easy, if your dream doesn't seem unrealizable to others then, it is not big enough. Yes you heard me right, your dream should seem unrealizable to others never to your own self.
Your travel life has the aspect of a dream. It is something outside the normal, yet you are in it. It is peopled with characters you have never seen before and in all probability will never see again. It brings occasional homesickness, and loneliness, and pangs of longing... But you are like the Vikings who have gone into a world of adventure, and home is not home until you return.
