You never know what motivates you.
Who seeks shall find.
Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
Always desire to learn something useful.
It's always too early to quit.
Wherever you are - be all there.
If you're going through hell, keep going.
The secret of getting ahead is getting started.
Only the educated are free.
If global cooling will come soon - scientists will lose trust.
