Congrats on finding the airfield easily! The whole point of the solo nav during the PPL course is to give you the confidence in the techniques you are being taught. It is sometimes hard to believe that they work, which is why people sometimes resort to using a GPS or feature-crawling after getting their license - but if you follow the advice on this thread, all of your nav, dual or solo, will work absolutely fine without any fancy gadgets.
One other thing to add to the good advice already given, for your next nav trip - when you're looking for a turning point, make sure you study your chart and identify features which will uniquely identify it.
For example, there's a town near to my home airfield which I take most of my students to. Most of them identify it by saying it lies next to a motorway and a railway line. That's true, it does - but so do the next three towns. When I ask my students how they can be sure it's not some other town, they usually run out of ideas.... until I point out the relationship of the motorway and the railway. Alongside the town, they are right next to each other, but just a mile or so north of the town, they split apart in a "Y" shape - a feature which is unique to this particular town. That's the kind of feature which gives you the confidence in your navigation.
