Wow! "As the gap of knowledge widens, knowing what you don't know turns into not knowing what questions to ask in order to fill the gap... and then it slips into not knowing what you don't know."

Haha I think you're the thought provoking one here ;)

Yeah I think many of us have regrets like that and want to "time-travel" back to that time and buy on the cheap. The important thing is to keep that as a reminder and use it as acquired experience for the next time.

Thanks for the amazing comment man.
