Quote of the day by Marcus Aurelius that has 'inspired' Elon Musk: 'You have power over your mind, not outside events; realise this, and you will find strength'

Some quotes travel through centuries and arrive in the present moment feeling more relevant than when they were first written. This is one of them. Marcus Aurelius, the Roman Emperor who ruled from 161 to 180 AD and whose private journal of Stoic reflections has survived nearly two thousand years to become one of the most widely read works of philosophy in the world, wrote with a directness that cuts through the noise of any era. The quote is not comfort. It is instruction. And it has found a new generation of admirers, including some of the most powerful figures in contemporary business and technology.
