In 1904, Capetillo began to write essays, titled Mi Opinión (My Opinion), about her ideas, which were published in radical and union newspapers.

[3] Luisa Capetillo was greatly influenced by her parents, her environment, her personal experiences and the literature she surrounded herself with.

She strongly sided with George Sands' beliefs that the old liberated woman could be "revolutionary, both politically and in her personal life, opposed to marriage and to all social contracts that would regulate human relations, but willing to sacrifice everything in the name of love".

Later on, Luisa would dedicate the following words to her mom: "To you, dear mother of mine, who tried to control me, or make me think traditionally.

She read much of French writers like Victor Hugo and Émile Zola and of Russian Romantics like Leo Tolstoy.

In a letter she wrote to her daughter she advised her that in order to be considered good, she didn't have to attend Mass.

In 1910 she became a reporter for the "FLT" (American Federation of Labor) and traveled throughout Puerto Rico educating and organizing women.

[10] Capetillo started a program of reading to the women who worked 12 hour shifts on the shop floor making cigars.

[12] In 1912, Capetillo traveled to New York City, where she organized Cuban and Puerto Rican tobacco workers.

In July 24, 1915, she challenged the mainstream society by becoming the first woman in Puerto Rico to wear pants in public.

She would repeat this act of rebellion again stepping off the boat into Cuba where the judge was not so lenient leading to her serving time.

In that same year, along with other labor activists, she helped pass a minimum-wage law in the Puerto Rican Legislature.
