These are noble guidelines. How to apply them in daily life, or “practical application” is key. That’s a pretty broad and yet subjective question.
Based on one’s charism, vocation, and personality, you’re painting with a very broad brush.
I’m reminded of the latter half of the verse of Matthew 6:34, “Sufficient unto the day is the evil thereof,” or, “Sufficient for a day is its own evil,” and even a reflection on today’s Gospel:
Luke 13: 1-9: One day some persons told Jesus what had occurred in the Temple: Pilate had Galileans killed and their blood mingled with the blood of their sacrifices. Jesus replied, "Do you think that these Galileans were worse sinners than all the other Galileans because they suffered this? I tell you: no.
But unless you change your ways, you will all perish as they did. And those eighteen persons in Siloah who were crushed when the tower fell, do you think they were more guilty than all the others in Jerusalem? I tell you: no. But unless you change your ways, you will all perish as they did."
And Jesus continued with this story:] “A man had a fig tree growing in his vineyard and he came looking for fruit on it, but found none. Then he said to the gardener: ‘Look here, for three years now I have been looking for figs on this tree and I have found none. Cut it down, why should it use up the ground?’ The gardener replied: 'Leave it one more year, so that I may dig around it and add some fertilizer; and perhaps it will bear fruit from now on. But if it doesn’t, you can cut it down.”
If one can learn to offer up what befalls him (or even the consequences of his actions) with charity and grace, then I think a person can attain, or even
is, holy. We have Christ, the spotless and final Paschal victim, the gardener in the parable, interceding for us.
I think your list is a comprehensive set of high-level ideals

, but I’d revise it based on priority. I’d also like to add, “Dealing with adversity with appropriate humility relative to one’s station.”
We are the fig trees in the parable, and we’ve been given the chance to bear fruit in the cycle of another whole season (thankfully). To be holy does not require that we do anything heroic above and beyond what we are supposed to do. Now, if we are capable of going above and beyond, we should at least try. But for now, I’m God’s little fig tree, and I have little fruit, if any. I’m no less “holy” than any tree that has been producing large fruit for years.
