Copy?

In all worlds, in all fields, there's the copier. It's very easy to understand what is copy and how to do it, that means you imitate what other people had done. In school life, in work, in designing, in study, in all things.
People try to copy others all the time. The great work, the idea, etc..
Also, when you have some archivements, if you copied it from a person, you might be caught as a thief, but if you collect many ideas from many people (no matter what kind of idea or no matter who), you're called a scientist.
Is it true? Since we create something based on other ideas and works? Then we should not use the word "create" often. Just some basic and true words like "optimized", "better", "modified" ... not something like "innovation" or "discover" if it's not.
Jumping into the deeper world.
Einstein once again shows us his intelligence. Here's why:

“The secret to creativity is knowing how to hide your sources.” —Albert Einstein
