Be kind whenever possible. It is always possible.
You never know what motivates you.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
Only the educated are free.
If you've got a talent, protect it.
If you can dream it, you can do it.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
Either you run the day or the day runs you.
Science is wonderfully equipped to answer the question 'How?' but it gets terribly confused when you ask the question 'Why?'
