How to Become an Inventor
As middle school students, we need to do the following things to become an inventor.

      First, we must study hard to gel more 
knowledge. It's important for us to invent 
anything with knowledge. Second, we should 
have an interest in inventing. When we are 
interested in something, we can do it well. 
Third, we need to be creative. We should
always come up with new ideas. Most
importantly, we should keep on and never
give up.
