'Wander Theory' is something that came out of my masters project back in 2012. It is a fractal pattern applied to roads from large roads to small tracks. If you stay on the large roads, you get there quickly and more assuredly but you see less stuff and have less chance for serendipity and chance meetings to occur.
If you, on the other hand, stray from the course and keep straying, you will likely end up somewhere completely different and likely not reach your goal. I think the goal is still important. The goal represents imagination which you need to decide your journey.
