Today, the start of the Persian New Year begins a two week period of celebration. In 1912, Abdu'l-Baha could not afford to take two weeks off from his efforts. He continued to share with residents of the United States information about the Baha'i Faith.
Here is a quote for Abdu'l-Baha. It shows how his thoughts provided him with the motivation to keep going.
".....Cleanse ye your eyes,
so that ye behold no man as different from yourselves.... See ye no strangers;
rather see all men as friends, for love and unity come hard when ye fix your gaze on otherness...." Selections from the Writings of Abdu'l-Bahap. 23
