You Have to start to be Great

We could never learn to be brave and patient, if there were only joy in the world.

We have two ears and one mouth so that we can listen twice as much as we speak.

Nature shows that with the growth of intelligence comes increased capacity for pain, and it is only with the highest degree of intelligence that suffering reaches its supreme point.

There is only one corner of the universe you can be certain of improving, and that's your own self. 

It is not in the stars to hold our destiny but in ourselves.
