The question of whether you would be successful and happy living off the grid and in the country is an important matter and should be carefully considered. While there are many advantages and conveniences to country living, there are also some inconveniences to which you may not be accustomed. Life in the country is different than life in the city or suburbs, but, strangely, the very things that you may at first dislike most about the country come to be the things that you most cherish.
In the long run, it will not be inconveniences or isolation that will determine your overall happiness about living in the country and off the grid. On the contrary, your success and happiness will come as a natural consequence of your labor and your self reliance.
