How are Burns’ poem and Steinbeck’s novel similar

Robert Burns and John Steinbeck are two authors who brilliantly capture the disappointment that follows failed plans.  

Robert Burns' poem, 'To a Mouse' was the inspiration for the title behind John Steinbeck's 1937 novella, Of Mice and Men. Set in the 1930s during the Great Depression, Steinbeck plays on Burns' idea of shattered dreams and failed plans through the characters of this classic work.
