Thomas Edison invented the advanced light bulb with little help from modern technology.When light bulbs were first invented in the 1800s, they only burned for a few minutes. Manyinventors had tried but failed to make a light bulb that would burn for a longer time.       Edison was already a successful inventor when he began work on the light bulb. Afterfailing thousands of times, Edison still didn’t give up. Instead, he discovered that tiny pieces ofbamboo covered with carbon would work well. So he sent a man to Japan to get the bamboo.The process must have taken years, but Edison waited patiently. As a result of his patience andhard work, he successfully invented the better light bulb that lights up our homes every day.        If people think you are crazy for spending too much time on something that you are creating,don’t sweat it； maybe you are the next great inventor! As Edison would have said, “Genius is 1% inspiration and 99% perspiration.” Just keep up your goal and make it come true.
