Novelty, Creativity, Innovation and Invention

First of all, again what is creativity??... Well creativity means the ability to create new ideas and make it to be a reality from your thoughts. As a creative student I think that not only me but most of the people outside there especially the inventors should think creatively to create something that is very useful to everyone. The new word I learnt in class was novelty. It is about the quality of being new. Meanwhile Invention is the formulation of new ideas for products or processes and on the other hand Innovation was all about the practical application of new inventions into marketable products or services. Why is this all important??... Well everyone should know about all these things if they wanted to be a good inventor. As an inventor they should create creative products which will be very useful to everyone.
