I'm going through a strange period now. Maybe the most serious of all my short life. I can see that my goals are becoming more and more remote from those of the family, and that you and they will be less and less inclined to approve of them... And still I must go on. I must not retreat. I struggle forward, just as all of you do, but I'm doing it within my own mind, my own skin, and in the way I think is right. I'm little frightened by my loneliness in my unguarded hours. But personally those are the very hours that help me along toward my goal. You needn't show this letter to our parents.

In a letter to her sister Milly (21 September 1899); as quoted in Voicing our visions, – Writings by women artists; ed. Mara R. Witzling, Universe New York, 1991, p. 199
