Always desire to learn something useful.

By failing to prepare, you are preparing to fail.

You never know what motivates you.

Problems are not stop signs, they are guidelines.

Be gentle to all and stern with yourself.

The wise does at once what the fool does at last.

Go for it now. The future is promised to no one.

To know oneself, one should assert oneself.

Quality is not an act, it is a habit.
