“Self-development is a higher duty than self-sacrifice.”
Stanton challenges a moral standard that praises women mainly for self-denial, arguing instead that developing one’s capacities is itself an important obligation.
Source note: The Woman’s Bible, Stanton commentary; the line appears in her critique of idealizing women’s self-sacrifice and is preserved in the Project Gutenberg text.

“I am larger, better than I thought, I did not know I held so much goodness.”
Whitman describes self-discovery as expansion rather than invention: experience reveals capacities and goodness that were already present but insufficiently recognized.
Source note: Song of the Open Road, section 5, after the speaker describes loosening imagined limits.

“Every individual is a marvel of unknown and unrealized possibilities.”
Jordan locates worth partly in capacities that have not yet been discovered or developed, resisting a final judgment based only on present performance.
Source note: Self-Control, Its Kingship and Majesty, later discussion of individual possibility. The sentence is motivational rhetoric about human potential rather than a measurable universal prediction.

“My first duty is to develop all the powers given to me and to make the most of myself and my own life.”
Voice: Imagined speaker · Jephthah’s daughter (imagined by Stanton)
The imagined speaker refuses to let another person dispose of her life, grounding dignity in the responsibility to develop her own capacities and possibilities.
Source note: The Woman’s Bible, Stanton’s commentary on Jephthah’s daughter; this sentence is part of an imagined protest Stanton writes for the unnamed daughter, not a biblical quotation.

“Believe in yourself; you may succeed when others do not believe in you, but never when you do not believe in yourself.”
External encouragement can help, but Marden makes self-belief the non-substitutable part of action: progress is difficult when a person has already decided internally that success is impossible.
Source note: How to Succeed, chapter “Hold Up Your Head,” in the Project Gutenberg text; the book’s period language and success philosophy are preserved as historical self-development writing.

“The Ideal is in thyself”
Voice: Fictional narrator · Diogenes Teufelsdröckh (framed voice)
The phrase turns the search for an ideal life inward, arguing that a person’s task is to shape present circumstances through capacities and standards not supplied wholly from outside.
Source note: Sartor Resartus, Book II, Chapter IX; Project Gutenberg #1051. The surrounding passage is highly rhetorical and spoken through the book’s fictional-philosophical construction rather than as a plain autobiographical maxim.
