I have a terrible sense of direction and frequently struggle to know which way to head when I exit an underground station. I can use the map on my phone of course (though there are some places this wouldn’t be safe), and if it’s not nighttime or cloudy, the position of the sun helps, but I’m
often 90 degrees or more out in my reckoning.

What tactics can I adopt to help me orient myself for my ongoing travel (on foot)?
