Enthusiasm is your joy and liking what you are doing. Of course not everything is enjoyable or something you will be enthusiastic about. However, the more enthusiasm you feel for what you are doing the more often you will feel positive and be motivated. When you are enthusiastic, other people pick up on your vibe and may also become enthusiastic with you. Enthusiasm is an emotion transferred and spread among people. Recognize your own enthusiasm. You will feel good and encourage others.
