If I were to go to Portugal for a month long stay I would begin by researching the country and customs. I would search out contacts on the ground. Perhaps local guides, or expats who know the area well. Establish an online relationship with them and make queries about where to stay, and details of historical and cultural attractions. I would ask about "off the beaten path" local hang outs and restaurants. Local bars and cafes that envelope the local charm and culture. I would like to know what the people do for work, what they do on their days off. How they shop for food and provide for their family. What the transportation and communication infrastructure is like. What the favourite foods and drinks are and how much things cost.
After carefully selecting a quiet "headquarters" for my month long stay, I would spend a day or two networking with my contacts and filling in the blanks on my schedule. I like to travel light, so just a pack containing my necessities along with my laptop and cameras will help me document my stay. As a matter of discipline I would like to write or work in some way from my laptop for at least one hour per day. This may vary depending on my schedule.
Becoming embedded in the local scene is my goal. I want to keep myself open and receptive to all types of adventure. Anything that I could document and share with my community at home and around the world. Local Holidays or events as well as food and entertainment are all things I would be taking in and writing about daily.
I would volunteer in community initiatives and charities to do my part and gain more experience about the local culture and to meet more people.
Besides being in Portugal and experiencing all it has to offer, my personal goal has always been to have the freedom to travel on my own terms. Downsizing to be come independent and stay as long as I like, without outside incumbencies is my ultimate goal. I would earn an income from my online work and live a simpler life always having another adventure on the horizon.
