It's always too early to quit.

After a storm comes a calm.

What you do today can improve all your tomorrows.

Things do not happen. Things are made to happen.

Do not weep do not wax indignant. Understand.

To know oneself, one should assert oneself.

Be thine own palace, or the world's thy jail.

Problems are not stop signs, they are guidelines.

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