Frederick Douglass used a number of strategies to continue his education after his mistress's abandonment. These strategies included:
Sneaking away to read at night. Douglass would often sneak away to read at night, even though he knew that he could be punished if he was caught. He would often read by candlelight, and he would often hide his books in his bed or in his clothes.
Paying for lessons. When he was able to, Douglass would pay for lessons from other people. He would often pay for lessons from white people, even though it was illegal for slaves to learn to read and write.
Teaching himself. Douglass was also able to teach himself a great deal. He would often read books that he found in the trash, and he would often ask questions of other people. He was a very quick learner, and he was able to teach himself a great deal of knowledge.
Douglass's determination to learn was remarkable. He faced many obstacles, but he was able to overcome them all. He was able to educate himself, and he was able to use his education to become a powerful advocate for the abolition of slavery.
