If you are blind don't think you don't have a future. Helen Keller was also blind still she became one of the most influential writer of all times. If you are deaf don't think you don't have a life. Beethoven was also deaf but he is the greatest musician. Still his symphonies are played worldwide. He said, "misfortune is I can't listen to my own music but the fortune is I'm deaf but still compose music."
You must have listened his symphonies too in Mr.Bean, Tom and Jerry, Bugs Bunny and all the cartoons you watched in childhood. If you are suffering a severe disease don't give up because Remberandt was a great painter of his time and he suffered many severe diseases. If you are dull or not intelligent don't give up hope. Edison couldn't write correctly, Michal Faraday left school, Einstein was expelled from school. Today we all know them. Every energy saver or LED lights is the result of Edison's efforts, every device converting electricity to mechanical work is the consequence of Faraday's work and we all are familiar with the term relativity. And if You suffer in the way of knowledge don't get carried away. Copernicus was made ride a donkey in the while city and was burnt to ashes in front of everyone. Darwin was thrown in prison and was killed there. Espinosa was kicked out of his city. But when Copernicus died he died with dignity. Today, we all know the earth revolves around the sun. It was predicted by him for the first time and was killed because of it. Darwin said just moments before he was killed, "one day there will be many followers of my idea." Espinosa was developed the base of atheism. Today, half of the world believes in evolution theory. Atheism has become one of the fastest spreading belief. I don't want to make an argument that being an atheist is a good thing or evolution is true or not. I just want to say doesn't matter how much you suffer but if you struggle you will be remembered. The key to success is, "don't give up."
