Bross, "I am not well" -- referring to his "melancholy," known today as depression.

It turns out that Lincoln used his depression and self-doubt as a strength. "Lincoln's self-negation fueled his peculiar confidence. His despair lay under a distinct hope; his overwhelming melancholy fed into a supple creative power. ... Wariness and doubt led Lincoln into a kind of personal crisis, from which he turned to work," wroteThe Atlantic．

Edith Wharton

Another famous writer that struggled with self-doubt and esteem was Edith Wharton. While she grew up in a wealthy household, Wharton not only felt self-conscious of her ability and right to write, she also felt inferior to most of her peers. As she wrote in her autobiography,A Backward Glance: "I have often wondered, in looking back at the slow stammering beginnings of my literary life, whether or not it is a good thing for the creative artist to grow up in an atmosphere where the arts are simply nonexistent. Violent opposition might be a stimulus -- but was it helpful or the reverse to have every aspiration ignored, or looked at askance? ... I am inclined to think the drawbacks were outweighed by the advantages; chief among these being the fact that I escaped all premature flattery, all local celebrity, that I had to fight my way to expression through a thick fog of indifference, if not tacit disapproval."
