What is the main theme of william kamkwamba's story? what led you to this conclusion? briefly explain in two or three sentences. use proper spelling and grammar. (story included)

The main theme of William Kamkwamba's story is that sometimes from the humblest beginnings, great things are achieved.  What led me to this conclusion is that Willaim came from a very poor background and he had nothing, but he did not give up, he kept going even though it was hard. William did not give up or lose his hope even though it was hard and it led him to great success.
