In Africa there is the concept of Ubuntu "I am because we are". Identity and personhood arises within community, rather than being constructed indivudually.
I think we need to differentiate between self-help in the modern sense, and viewing the self as a continuous process of engaging in meaningful activities, within community, with purpose that helps cultivate virtue. i.e "Becoming"
When self-help is treated as only individual optimisation, without any ultimate end it risk becoming self-referential.
Philosopher Charles Taylor describes a similar shift with modernity that he calls "Disengaged reason" [0]. Where reason is disconnected from moral frameworks, that once helped orient us.
The deeper issue may be Self-help/Improvement that is often not contained within these larger frameworks of meaning, that answer:
To what ultimate end?
