It's always too early to quit.

If you think you can do it, you can.

To know oneself, one should assert oneself.

Well done is better than well said.

Things do not happen. Things are made to happen.

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

Be gentle to all and stern with yourself.

Problems are not stop signs, they are guidelines.

Do not weep do not wax indignant. Understand.
