The most important thing is our love for each other. We should strengthen the clarity with which we see the immeasurable worth of each person and to regard and treat them with the utmost love without conditions. We should also believe in them beyond measure and without fail. We should strive to treat them with profound care and to desire their well being on all levels and their happiness and their relief from any suffering. We should respect their boundaries and approach them with respect and sacred regard.
Every person at their core and root is emanating from HaShem in perfectness, and is loved by HaShem, and loves HaShem entirely. The ways we stumble and get mired in this world do not reach that core - ever. Like a person loves their small child, and if they might trip and hurt themselves not only does this not reduce the parent's love for their child at all but causes their love to well up in concern while rushing to their aid with care - so should we aim to rightly respond to every person, stumbling or mired as they might be, as we all are in our ways and in our times. This, as I understand it, is one explanation of the meaning of "Magen Avraham".
We are meant to love each other in this way and then exert ourselves to put that into action. In this way we emulate HaShem - "Who supports those who fall, heals those who become ill, frees those who become trapped, and remains faithfully there for those asleep in the dust... Who brings back to life those who have died."
When we grow in this area, that itself is drawing nearer to HaShem.
All of our studies and prayers, and the thoughts, feelings, and actions that follow from them, should only add to this love, identification, and profound regard which we have for every person. If instead these qualities are being diminished then we need to repair something in our studies or prayers.
