The Consideration by Saint Bernard is of course required reading for every Pope. There are great things in it, too, for example: Remember that you are not the successor of Emperor Constantine but rather the successor of a fisherman.
The basic theme is the one that you have noted: Do not become utterly absorbed in activism! There would be so much to do that one could be working on it constantly. And that is precisely the wrong thing. Not becoming totally absorbed in activism means maintaining consideratio, discretion, deeper examination, contemplation, time for interior pondering, vision, and dealing with things, remaining with God and meditating about God. One should not feel obliged to work ceaselessly; this in itself is important for everyone, too, for instance, for every manager, too, and even more so for a Pope. He has to leave many things to others so as to maintain his inner view of the whole, his interior recollection, from which the view of what is essential can proceed.
