Nothing great was ever achieved without enthusiasm.

Life's blows cannot break a person whose spirit is warmed at the fire of enthusiasm!

The great accomplishments of man have resulted from the transmission of ideas of enthusiasm.

Think enthusiastically about everything; but especially about your job. If you do, you'll put a torch of glory in your life. If you love your job with enthusiasm, you'll shake it to pieces. You'll love it into greatness, you'll upgrade it, you'll fill it with prestige and power.

Enthusiasm is that kindling spark which marks the difference between the leaders in every activity and the laggards who put in just enough to get by.

Never be bored, and you will never be boring.

When you are enthusiastic about what you do, you feel this positive energy. It’s very simple.

Faith is an excitement and an enthusiasm: it is a condition of intellectual magnificence to which we must cling as to a treasure, and not squander.
