Be gentle to all and stern with yourself.
Do not weep do not wax indignant. Understand.
Begin to be now what you will be hereafter.
Go for it now. The future is promised to no one.
Wherever you are - be all there.
Expect problems and eat them for breakfast.
Know or listen to those who know.
If you've got a talent, protect it.
The wise does at once what the fool does at last.
Always desire to learn something useful.
Science is wonderfully equipped to answer the question 'How?' but it gets terribly confused when you ask the question 'Why?'
