It is not enough to have great qualities We should also have the management of them.

After climbing a great hill, one only finds that there are many more hills to climb.

The great thing in the world is not so much where we stand, as in what direction we are moving.

Most great people have attained their greatest success just one step beyond their greatest failure.

One sees great things from the valley only small things from the peak.

All great and beautiful work has come of first gazing without shrinking into the darkness.
