Here are some beautiful lines on a word which depicts the tale of huge sacrifices to be done for its attainment and that is -

EXCELLENCE

.

.

We are what we repeatedly do.

Excellence, then, is not an act, but a habit.

-Aristotle

.

.

Excellence can be obtained if you:

....care more than others think is wise;

....risk more than others think is safe;

....dream more than others think is practical;

....expect more than others think is possible.

-Author unknown
