He was home-schooled, and he began a lifelong naturalist avocation before attending Harvard College. Roosevelt gave up his earlier plan of studying natural science and instead decided to attend Columbia Law School, moving back into his family's home in New York City. Roosevelt was an able law student, but he often found law to be irrational. He spent much of his time writing a book on the War of 1812.Determined to enter politics, Roosevelt began attending meetings at Morton Hall, the 59th Street headquarters of New York's 21st District Republican Association.
