New technology provides the answer!
Finding your way should be straightforward if you download and use tracks that others have done on a GPS unit or to your smartphone (have a smartphone with a removable battery a few backup batteries, though, as the GPS sucks power relatively quickly). You can simply reverse the track and then follow the arrow.
If all of this means nothing to you, it's not too difficult to learn with the help of Google and YouTube. Start by downloading a track for somewhere close to where you live, find a guide online on how to put this on your phone and what app to use (I use mapps.me, Geo Tracker and GPX viewer on my Android) then follow the track, then reverse it and follow it back. You'll soon get the hang of it.
