" Enthusiasm makes the difference." 

~~Dr.Norman Vincent Peale~~

What this quote is saying is that when your enthusiastic you have more energy you have more fun and you have more excitement towards things. When you are not enthusiastic you don't have energy to do things you find everything boring. When you are enthusiastic things are more fun to do you want to keep doing them over and over again, most people when they are enthusiastic they are most likely to be a positive and happy person. Enthusiasm can make a difference because it can make you look at things in different perspectives like the things that are boring to other people are fun to you when people are sad your enthusiasm can make them happy or put a smile on their face. You can spread happiness and positive energy to others that are sad and negative about things or life. Its like if you were to sell an item or product you wouldn't want to buy it from a person that just talks and talks about the product and makes it seem boring and not interesting to buy but instead you want to buy the product from a person that is enthusiastic about selling the product and making you want to buy the product.
