The meaning of the word "Expert"

This is just a part of the definition:
"....Experts use better tools and care deeply about their craft. They aren't assembling bits on an assembly line, they are crafting a unique product to solve a unique problem. Experts are lazy, they work smarter rather than harder. Experts prefer the easiest solution that gets the job done. Experts aren't interested in creating complex solutions simply to have the complexity, that misguided egoism is the territory of more junior developers. They often get it right the first try and almost always on the second one...."
