It's always too early to quit.
Problems are not stop signs, they are guidelines.
Who seeks shall find.
The wise does at once what the fool does at last.
After a storm comes a calm.
Know or listen to those who know.
By failing to prepare, you are preparing to fail.
Be kind whenever possible. It is always possible.
To know oneself, one should assert oneself.
Either you run the day or the day runs you.
In high school, we studied a lot of poetical forms. I was really interested in the math that was involved and the strange live break ups. That gave me a great amount of respect for a rhymed stanza.
