If you think you can do it, you can.
You never know what motivates you.
After a storm comes a calm.
Who seeks shall find.
Go for it now. The future is promised to no one.
It's always too early to quit.
Expect problems and eat them for breakfast.
Know or listen to those who know.
Always desire to learn something useful.
Either you run the day or the day runs you.
We now witness the constructive work on a foundation that will endure through the ages. That foundation is the god of science - revealed to us in terms that will harmonize with our intelligence.
