"Enthusiasm makes the difference." 

Dr. Norman Vincent Peale

Enthusiasm, in some cases, may make you a better person, and in some cases it can give you an "edge" in competition. When your enthusiastic about a school assignment you'll most likely do it without feeling forced. Enthusiasm, as far as I understand, simply means having motivation to do something and being energetic/happy about what you're doing. I think it is very hard to be enthusiastic about some things, for example, cleaning up after pets and siblings becomes a hassle and for some people, the repetitive activity becomes more and more boring. In order to have enthusiasm for something you have to look at it in a different light. I believe with time and patience a person can develop enthusiasm for things as they please.
