Agreed.
Your only important job in the opening is to reach a middle-game position in which you feel comfortable and confident.
That's it.

It depends. In my last OTB tournament, there were multiple games where knowledge of opening theory was critical to the result of the game. But that was because I was playing some very theoretical openings. If you're playing the hippo, on the other hand, you probably ought to forgo studying concrete lines, and to study middlegames instead.
