After a storm comes a calm.
Problems are not stop signs, they are guidelines.
It's always too early to quit.
Expect problems and eat them for breakfast.
Who seeks shall find.
Know or listen to those who know.
By failing to prepare, you are preparing to fail.
The most effective way to do it, is to do it.
Always desire to learn something useful.
Without hard work, nothing grows but weeds.
There is no single development, in either technology or management technique, which by itself promises even one order-of-magnitude improvement within a decade in productivity, in reliability, in simplicity.
