I don't believe a book or anything similar can keep me "motivated" (that depends on one's will and outlook), but some can definitely help. A very influential text that helped me advance quite a bit in shaping my world view was the Anarchist Banker of Pessoa. It gives an interesting answer to the question of "existing in a world as a single individual that can hardly ameliorate the world on his own". Combining that with a reading of "Existentialism is a Humanism", and general free thinking, do help to build a strong defence mechanism to the facts of the outer world that can demotivate you. I'm quite an outlier in this community of mostly engineers and entrepreneurs, groups with which my thoughts usually conflict (especially the latter ones), but reading philosophy and philosophically-charged literature can furnish a sort of critical thinking, skepticism and/or quasi-nihilism that can actually boost one's confidence in pursuing some ends.
