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

Be gentle to all and stern with yourself.

If you think you can do it, you can.

It's always too early to quit.

Do not weep do not wax indignant. Understand.

Problems are not stop signs, they are guidelines.

If you can dream it, you can do it.

To know oneself, one should assert oneself.

Always desire to learn something useful.
