I have become a fan of Sky Matsuhashi and his channel, SmartPokerStudy
This is one of his oldest videos but it is still a terrific summary of VPIP and PFR stats - hope it helps you to understand where you want to be, and why. Each player in poker will have a different idea of how they wish to play the game (tight or loose, aggressive or passive) and thus, we will all have different stats to shoot for... and if we're good at adjusting to the table conditions, we should be able to play with a different style each session we play, depending on how our opponents are playing at that time and at that table.
