A map is an empty canvas for your to explore your options. The route chosen serves as a guide not a detailed plan. First steps to choosing a route starts with picking a start and a finish location (sometimes the same). I believe having a start and finish gives a goal and an achievement to both work for and look forward to either through excitement or just as a sigh of relief.
I don’t like the idea of aimlessly cycling around unless you have a list of places you want see. That’s my opinion, but I prefer seeing a transition of change between regions or countries.
