Every memorable act in the history of the world is a triumph of enthusiasm.
Nothing great was ever achieved without it because it gives any challenge or any occupation, no matter how frightening or difficult, a new meaning.
Without enthusiasm you are doomed to a life of mediocrity but with it you can accomplish miracles.
-- Og Mandino (1923-1996)
If you want to be successful in your field of study, being interested and having enthusiasm is the key.
