Deliberate off track
All great tips. If I may add one consider setting a deliberate off track heading:
Say you're travelling East to an impossible to find feature like a tree in the shape of a Y along a fence running North - South. Rather than navigating like a devil fretting about perfect GS and perfect 1 in 60s just intentionally fly a bit to one side and then when you reach the fence you know that if you're not at the feature you must be to the North or South (allow the off track to affect you the same as an otherwise uncorrecte crosswind i.e. all factors sending you a bit to the same side). At best you happen upon it at the perfect time, at worst you then fly an extra minute rather than 5 or 10. It's worked well for me.
Anybody disagree (not looking for an argument, just interested).

Oh, and Google Earth is not cheating, not for PPL anyway (you may or may not have time to Google Earth on your CPL exam... I did and I still ballsed it up).
