Anger, sadness and pessimism aren’t divine cruelty or sheer random bad luck – they evolved to serve useful functions and help us thrive. From Newton’s obsessive grudges to Beethoven’s tantrums – which sometimes came to blows – it seems as though visionary geniuses often come with extremely short tempers. There are plenty of examples to be found in Silicon Valley. Amazon founder Jeff Bezos is famed for his angry outbursts and insults (such as “I’m sorry, did I take my stupid pills today?”) yet they haven’t stopped him building a $300 billion company.
