How to become a successful inventor

Lots of people like to invent something that changes the world, but did you know that most inventions fail?
Yes, only a small number of inventions are used by people, and all the other ones are ignored.
Here are what you should do to be a successful inventor.

(1) ................................ Having a good imagination is important, but we also have to look around us too.
Find a problem that people have and try to come up with a solution.
Soon you will start having new ideas about what can help solve the problem.

(2) ................................ Before you show your invention to people, you have to test it several times –
maybe hundreds of times. People will not like your invention if it does not work.
First, you need to build the first version of your invention and then improve it little by little.

(3) ................................ It is very important that you register your idea and invention with a patent office.
If you do not do it, someone else may steal or register your idea.
Then you cannot sell your invention without their permission. It is a big world.
Maybe another person is working on the same invention as yours!

(4) ................................ See if there are any customers for your inventions.
Many inventors spend all of their money on their inventions, but only a few people buy them.
You do not want to go broke, do you?
