When I was doing this not very long ago, I found that there were a few things that gave me some basic confidence.
The first was really detailed planning and putting the details on the chart as I was taught, no short cuts. The fan lines in particular were a big help in looking for features and I used features way points. Note that you won't see features if you fly over them, so the fan lines help you to spot useful landmarks either side of your track.
The second was FREDA checks especially DI and Compass alignment and then you can recheck your drift about every 10 mins or so at features.
The third was asking other pilots how to spot the other airfield when I got there!
Good luck! I was so chuffed after my first solo landaway it was ridiculous!
