“work hard to find something that fascinates you”: richard feynman’s advice to students

I’ve found some lovely snippets from this book of Richard Feynman’s letters after only a few pages:

• “Work hard to find something that fascinates you”
• “study hard what interests you the most in the most undisciplined, irreverent and original manner possible”
• “I think it’s much more interesting to live not knowing than to have answers which might be wrong”
• “Don’t pay attention to ‘authorities’, think for yourself”
