You never know what motivates you.
Leap, and the net will appear.
If you can dream it, you can do it.
Know or listen to those who know.
Either you run the day or the day runs you.
The wise does at once what the fool does at last.
Without hard work, nothing grows but weeds.
If you think you can do it, you can.
The dog that trots about finds a bone.
Things do not happen. Things are made to happen.
Science by itself has no moral dimension. But it does seek to establish truth. And upon this truth morality can be built.
