You will really start flying - and learning - after the PPL.
Oh, really?
What activities were you engaged in that entitled you to attain the PPL status?
I wonder why it is called "flight training" in the first place.
You did some solo flying as part of your program to attain your pilot certificate, right? Now, it would be prudent to reflect on that part of your flying in relation to your future flying engagements, to ascertain and understand the ramifications accordingly.
My assumption is that your flight training instructor provided you the information and advice (principles and practices) to fly a single engine airplane and that the flying skill set acquired during this phase will be applied in your future flying activities.
SO, why think that flying starts after PPL?
Make sure you're aware of your performance and safety margins before moving on, in order to avoid being part of aviation accident statistics.
Any pilot that thinks flying starts after PPL has doubt in his/her personal aviation capabilities.
