Who seeks shall find.
You never know what motivates you.
Leap, and the net will appear.
If you think you can do it, you can.
Things do not happen. Things are made to happen.
Be kind whenever possible. It is always possible.
Be gentle to all and stern with yourself.
Well done is better than well said.
If you've got a talent, protect it.
Do not weep do not wax indignant. Understand.
The diversity of the phenomena of nature is so great, and the treasures hidden in the heavens so rich, precisely in order that the human mind shall never be lacking in fresh nourishment.
