To know oneself, one should assert oneself.

After a storm comes a calm.

It's always too early to quit.

Without hard work, nothing grows but weeds.

By failing to prepare, you are preparing to fail.

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

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

Know or listen to those who know.

What you do today can improve all your tomorrows.
