Without his determination, Thomas Edison would not have been able to be the successful inventor that he became. It was his determination that made him get things done and never give up. Thomas Edison built his own laboratory in Menlo Park, New Jersey. "Menlo Park was the embryo of the modern research laboratory -- a place where the inventor could have at his fingertips the materials and expertise to turn his ideas into physical form," (http://americanhistory.si.edu). Thomas Edison was so determined to create his own inventions that he built his own lab and filled it with all the materials he could afford and with talented coworkers to help him. For many decades the scientists who tried to improve Humphry Davy's electric arc lamp were unsuccessful. "Edison was also driven to perfect a commercially practical incandescent light bulb. After making improvements in his design (as well as buying Woodward and Evans' patent in 1879), he was granted a patent for his own improved light bulb in 1879, and began to manufacture and market it for widespread use," ( http://www.biography.com). This shows that even though the other scientists failed in their attempts to create an effective electric light bulb, Edison was strongly motivated to invent one. It was his determination that helped him to reach his goal. "Not all his inventions were made easily, however. He worked on some for years and spent thousands of dollars in perfecting them. “Genius,” he said, “is two percent inspiration and ninety-eight percent perspiration,” (http://school.eb.com). Even though his inventions did not always go smoothly, Edison knew that he had to work hard on his inventions to get them right. As you can see Thomas Edison did not give up. He kept trying his hardest to achieve his goals and help more people with his inventions. Edison's determination helped him do so.
