Expect problems and eat them for breakfast.
Without hard work, nothing grows but weeds.
Be gentle to all and stern with yourself.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
The wise does at once what the fool does at last.
Leap, and the net will appear.
Well done is better than well said.
Quality is not an act, it is a habit.
It's always too early to quit.
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.
