Enthusiasts are adventurous, constantly busy with many activities with all the energy and enthusiasm of a child. At their best they grab life for its different joys and wonders and truly live in the moment but, at their worst, they dash head-long into life too fast.
The dictionary defines an enthusiast as a person who is highly interested in a particular activity or subject.
Some of the synonyms you may find are: addict, admirer, aficionado, believer, buff, bug, bum, devotee, eccentric, fan, fanatic, follower, freak, habitué, lover, maniac, monomaniac, nut, optimist, participant, partisan, rooter, supporter, votary, worshiper, zealot.
Well that’s just fine. Some of those words may describe you and that’s great.
