Being able to do the opposite of what is typically expected
Not being afraid of criticism
The mind not engaging in characteristic activities
Not chasing after fame and conventions.

Isn´t that a precious piece of contemporary "Blue Sky" life coaching advice?

Then I found the author quoting himself with small variation. In his second book, he calls it he "four necessities" (among three measures of confidence and five phenomena) to "cross over in non-doing"
The ability to reverse doing anything to accomplish [the fruition]
Not getting up in exxageration about or denigrating others
Not engaging the mind in characteristic activities
Not following after name and fame (page 861)
Advice to stay modest
And finally, advice to not show one-upmanship:
Having attained a little familiarity, the difficulty of not evaluating yourself as better than others: the ninth is, after having attained a little familiarity, the difficulty of not evaluating yourself as better than others, not thinking such thoughts and staying true. In generating humility you subdue the arrogance of the mind thinking "I know".
