    The biggest secret about inventing is that anybody can do it. It sounds crazy, but it's true. Maybe you have the wrong idea about inventing, so read on to discover the truth.

    Wrong idea No.1: An invention has to be something completely new.

    Inventing means creating something "new" , but the idea could come from something that already exists(存在). The Wright brothers, for example, got the idea of building a "flying machine" from watching birds.

    Wrong idea No.2: Inventors are born, not made.

    There are a lot of factors (因素) that make invention possible. Mozart was born with a talent for composition. But other factors were also important for his creativity. His father was a music teacher, and Mozart practiced for hours every day, from the time he was four years old.

    Very successful creators don't give up when they get something wrong.

    Wrong idea No.3: Inventors are always old people.

    Don't believe that you can't be an inventor when you are young. Here are two examples of young inventors Louis Braille went blind when he was a child. When he was fifteen, he invented a system of reading and writing for blind people that is still used in most countries today. As a young man, George Nissen was watching some artists performing in a show. He watched how they fell into the safety net and then jumped back up again. This gave him an idea, and he invented the trampoline (蹦床).

When he was a college teacher, he  think of a game that could be played in the winter.

In China, you can sometimespeoplebasketball in parks, schools and even factories.
