What is the author's tone in the memoir, One Day I Will Write About This Place?

More often than not, Wainaina’s tone in this novel is hopeful. There is one point in Chapter 15 where this is not the case. Wainaina falls into a deep depression that prevents him from being able to leave his room. This depression comes as Wainaina is trying to complete his college education at a university in South Africa. In places, Wainaina expresses his fear that he will not be able to succeed as a writer and that there will be nothing else that he will be fit to do.
