Enthusiasm is the genius of sincerity, and truth accomplishes no victories without it.

Enthusiasm is nothing more or less than faith in action.

Think excitement, talk excitement, act out excitement, and you will become an excited person. Life will take on a new zest, with deeper interests and greater meaning. You can talk, think, and act yourself into enthusiasm or dullness and into monotony or into happiness. By the same process you can build up inspiration, excitement and a surging depth of joy.

Success is going from failure to failure without loss of enthusiasm.

Enthusiasm is excitement with inspiration, motivation, and a pinch of creativity.

Each of us is born with a life purpose. Identifying, acknowledging, and honoring this purpose is perhaps the most important action successful people take. They take the time to understand what they're here to do — and then they pursue that with passion and enthusiasm.

Success is the ability to go from failure to failure without losing your enthusiasm.

What a man knows only through feeling can be explained only through enthusiasm.

I have studied the lives of great men and famous women, and I found that the men and women who got to the top were those who did the jobs they had in hand, with everything they had of energy, and enthusiasm and hard work.

Years wrinkle the skin, but to give up enthusiasm wrinkles the soul.

It is not the critic who counts, not the man who points out how the strong man stumbled, or where the doer of deeds could have done better. The credit belongs to the man in the arena; whose face is marred by dust and sweat and blood; who strives valiantly; who errs and comes short again and again; who knows the great enthusiasms, the great devotions, who spends himself in a worthy cause.

Enthusiasm ... spells the difference between mediocrity and accomplishment.

Knowledge is power and enthusiasm pulls the switch.

Enthusiasm is not an emotional state. It is a spiritual commitment, a loving surrender to our creative process. Enthusiasm — from the Greek, 'filled with God’ — is an ongoing energy supply tapped into the flow of life itself.

No one keeps up his enthusiasm automatically. Enthusiasm must be nourished with new actions, new aspirations, new efforts, new vision. Compete with yourself; set your teeth and dive into the job of breaking your own record. It is one’s own fault if his enthusiasm is gone; he has failed to feed it.

Every man is enthusiastic at times. One man has enthusiasm for thirty minutes, another man has it for thirty days. But it is the man who has it for thirty years who makes a success in life.
