" The Pythagoreans had been instructed to ‘never do anything without previous deliberation: in the morning forming a plan of what was to be done later, and at night to review the day’s actions’.13 Certainly, we can imagine that if we were to be bothered to practise both these morning previews and evening reviews, considering best approaches ahead of time and later holding ourselves to account, we would live and breathe these Stoic principles more effectively than a person who merely brings them half-remembered to mind when it is too late to fully benefit from them. It sounds, though, like a lot of work. It might, however, start with a thirty-second reminder to be the best person we can be, to not attach our emotional well-being to things outside of us, to watch out for known trouble spots; likewise, we can round up the day with as brief a look back at how we behaved, whether we let ourselves down, if there’s anything we should change tomorrow. It should be neither prescriptive nor arduous. A regular period of quiet solitude helps create a bedrock of self-sufficiency that accompanies us into the social hours ahead. As the addictive pleasures and miseries of electronic communication and phone-browsing offer themselves to us every minute of the day and night, we forget the benefits of time spent calmly with and within ourselves. If we are able to find time and space each day to redress the balance, and if we use it to remind ourselves that so much of our life has nothing to do with us, and that it is only with our thoughts and actions that we need to concern ourselves, we will soon find that our centre of gravity returns to its correct place.
