If a thing seems to you worth working for at all, if it appears to you of moment enough to challenge any effort, then put into what you do all the enthusiasm of which you are capable, regardless of criticism.
Enthusiasm will steady the heart and strengthen the will; it will give force to the thought and nerve to the hand until what was only a possibility becomes a reality.
What is enthusiasm but a passionate belief in what seems to be a high and holy aim - an unselfish devotion to some noble cause - a consecration of heart and mind and soul to the attainment of a great object?
