Be gentle to all and stern with yourself.
By failing to prepare, you are preparing to fail.
It's always too early to quit.
If you think you can do it, you can.
The secret of getting ahead is getting started.
Without hard work, nothing grows but weeds.
Wherever you are - be all there.
After a storm comes a calm.
Leap, and the net will appear.
Only the educated are free.
Science and technology revolutionize our lives, but memory, tradition and myth frame our response.
