Apart from what others have said here is not to panic, make large deviations or identify features as being what you want to see rather than what is there.
Double check towns and villages by checking for railway lines, rivers, shapes etc. check for features such as hills, lakes, coastlines.
Chances are you will be talking to someone if not make sure you are. If it is a military radar unit perfect, just tell them of your problem and they will no doubt help.
Even avoid a problem by telling them that you are a new PPL routing from A to B and can they keep an eye on you.
Even as an experienced pilot ATC are there for you to work.
Often under a radar service I will ask to be stepclimbed to a cruise level with airspace letting them sort out the controlled airspace or while flying IMC will ask for stears away from certain areas or aircraft.
So dont be shy of asking for help in the early days. It is reassuring to know someone is keeping half an eye on you until you have the confidence yourself.
