Ah the Tatras. I did my DofE there and when we were planning the route we kept getting the bearings wrong so in the end I drew massive arrows on the map pointing North so I wouldn't forget.
Four years later, I was helping to supervise a group in the same place who had walked all day in completely the opposite direction.
I rarely use the compass unless I can't see. Then I take a rough bearing and walk on it, I never really bother with variation or proper "walking on a bearing" techniques. I just sort of do it with an inbuilt sense of direction. One day I expect I'll come to some mischief but not yet.
