A thought from Aristotle:
Moral goodness, says Aristotle, is the result of habit. It takes time, practice, encouragement.
We can perhaps commit to give ourselves the time and practice, and hope that encouragement and guidance finds us.
The other related idea from Yoga philosophy: about practice. Where Aristotle's is an orientation and elevation towards goodness, this one, in the Yoga/ Eastern idiom is about restoring purity that is always inside. Just two outlooks to the same practice towards goodness and purity.
abhyasa - exercise, discipline; in Raja Yoga, this refers to "the (repeated) effort of the mind to remain in its unmodified condition of purity (sattva)." Ramana Maharshi sometimes refers to a spiritual aspirant as an Abhyasi - i.e. one who practices (uninterruptedly).
Again, the emphasis is on the practice - to again and again restore purity.

Tying it further to a not unrelated thought from Plato about beauty.
Beautiful objects have a really important function. They invite us to evolve in their direction, to become as they are. Beauty can educate our souls.
Along with beautiful objects, there are beautiful ways of being, of acting, of doing. In action and being, beauty in harmony, kindness, courage, generosity, calmness, independence, reasonableness, and such other ways of being. And in doing, in very local, subjective ways; in any little action done well, in harmony and fittingness of things - there are ways of doing everything which align with the beautiful.
To educate and elevate our souls, perhaps when possible, where possible to observe beautiful objects, beautiful ways, and then, by imitating (art), by practicing (art in motion, the ways), by recalling to mind, a practice of sorts.
Perhaps beauty allows the practice (of moral goodness, of purity), a guide, a rail.

The idea and hope is amongst these three ideas above, the mind finds its way to the state of beauty, truth, goodness, purity.
