A man must not delay his start in the right direction until the next day. Do not say: ‘To-morrow I will commence to serve the Lord properly; to-morrow I will begin to worship from the heart with all my strength.’ A man has only the day and hour in which he stands, and the morrow is a different world into which he enters. We read this in the Psalms (95:7): ‘Today, if ye would but harken to His voice.’
–Rabbi Nachman of Breslov, in Louis I. Newman, The Hasidic Anthology: Tales and Teachings of the Hasidim, 138
