The wise does at once what the fool does at last.
Be gentle to all and stern with yourself.
Only the educated are free.
The dog that trots about finds a bone.
Well done is better than well said.
Leap, and the net will appear.
Do not weep do not wax indignant. Understand.
By failing to prepare, you are preparing to fail.
Go for it now. The future is promised to no one.
Know or listen to those who know.
Science is wonderfully equipped to answer the question 'How?' but it gets terribly confused when you ask the question 'Why?'
