I'm a needle to DG transplanter.
I use the DG as a map in my head the centre being the station and a/c on tail of needle tracking up DG. then I ask 5 questions
Where am I?
Where do I want to be?
Which way do I turn to get there?
What heading do I turn to?
How will I know when I'm there?
Not only is the dg mind "map" used to work out where you are but also where you are in relation to where you want to be and thus the direction of turn os obvious.
If you go through the questions diligently each time its fairly hard to screw up (still possible tho!!!)
