Assuming that you are a car driver, just think back to when you learnt to drive.
I recall much the same feeling. How could I possibly remember to change gears, steer, look for hazards, read road signs, brake, indicate, and navigate, ALL at once?
Yet, once you have driven regularly for a few years, most of it comes automatically.
Believe me, the same does happen with flying. In my case (not a fast learner & not in the first flush of youth), I only really got reasonably confident, after about 200 hours.
The best advice I had, as soon as I had got my licence, was to team up with several other newly qualified PPLs at the same school, to share trips. This meant in the first year, after getting my PPL, I did over 70 hours, mostly on long cross-countries, including trips to France, Belgium, Netherlands, Channel Isles & Ireland.
So don't worry, it WILL all fall into place
