Know or listen to those who know.
If you think you can do it, you can.
Either you run the day or the day runs you.
The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
After a storm comes a calm.
The secret of getting ahead is getting started.
Expect problems and eat them for breakfast.
The most effective way to do it, is to do it.
Be kind whenever possible. It is always possible.
Science is a self-sufficient activity.
The thing about science is that it's an accurate picture of the world.
