G_String,
I don't think there is anything wrong being a humble pilot, in fact I think there is quite alot right with it.
Navigation is hard and it takes practice, but if you stick with it, it becomes easier and easier. I don't know what chart you use but I can highly recommend the quarter mil rather than the half mil. When I trained to fly, the half mil I thought I needed was never used (except for flight planning exercises) and I have used a quarter mils ever since. When planning identify features that you think might stand out along the way eg strange shaped woodland, towns, lakes etc and know where they are relative to you route. Finding airfields can be a little awkward, especially the likes of Fenland, but roads and other line features are useful. Finally (and I am sure this is trying to teach you to suck eggs) always orientate your map in the direction you are flying and make use of a DI or vertical card compass if it is fitted.
Enjoy the flying and remember when you crack the nav, imagine the confidence that will give you!
