I'm guessing that BOSE has been flying for a long time and has had lots of time to gain experience and knowledge. But with all due respect to him, how much did he know immediately after first got a licence?
I once heard a PPL described as a 'licence to learn' and that's exactly what it is. I've been flying for ten years and I'm lucky enough to be flying for a living these days - but I'm still learning. Almost every time I fly, I learn something new. That will probably remain the case for as long as I fly.
The most dangerous people are the ones who get a PPL and think that they know everything. The second most dangerous are the ones who get a PPL and think that they are expected to know everything and are afraid to ask about things they don't know in case they look silly.
Questions come up on this forum again and again which to experienced pilots like BOSE seem banal, unecessary and things which the people who posted them should have known the answer to anyway. Personally, I'm glad that this forum exists so that these questions CAN be asked.
