Sorry I'm kinda new, could someone plz explain this a tad more?

What is a manageable pot?

And why would you slow it down? To try to downplay your hand and get others to raise?

And a last thing.. what is the reasoning behind being slow if you're up front and being aggressive if you're at the back? Because you have more info about the other players?..

Sorry if my questions are annoying, trying to learn
