Once you decide that you wish to have your own log cabin, the first step is to start the research. It is very important to look into not only the cabin, but all aspects of the construction from land clearing through to building. Depending on where you are building your cabin these costs can be minimal or they can be very high.
Set your budget in a realistic way. Without a budget a log cabin, just like any other type of building, can quickly become a money pit. Don't go for every upgrade unless it is in the budget or you wish to make accommodations on some other feature.
