Just thought I'd give my own feedback as a current student of circa 20 hrs having just read your document
It's a great document and I like the friendly tone of the writing; really helps to make the whole subject more approachable. Also very reassuring, as someone not entirely brand new to this, to read your experiences and find they are very similar to my own, and many other people's I'm sure.
It'd be great to develop the document with more about what to expect from specific milestones and your personal experiences, e.g. what do you do on a check-ride? Yes it's a scary concept as mentioned, but it might help new and existing students settle in their mind what is coming up from the comfort of their home rather than in front of an instructor or examiner perhaps too nervous to think of or ask something.
Appreciate your document is more about the mindset of 'how' to learn to fly, but it might be useful
PPL Tutor also deserves a mention in the exams section. I pretty much used this exclusively to pass my exams and can't sing its praises enough!
