You mention navigation specifically. What you may not see from your present situation is that tablet based navigation apps have totally transformed cross country flying here, and in most other countries, in the last few years. Unfortunately there's still a culture that favours dead reckoning in flight training, a system of navigation that to be honest never really worked for PPL's. It seems to me that in those far off days that every flight involved some momentary 'uncertain of position' event, with quite a few people actually getting lost.
Today, with Foreflight, Sky Demon, et al., these events simply don't occur. You are never 'uncertain of position', although you may still have trouble spotting the airfield even when you know it's right under the nose. Just be sure to have a spare device (phone, etc) accessible.
I suggest you get a qualified PPL to show you how we navigate in the real world!
