There's never any closure in an awe-inspired life, only constant acceptance of the mysteries of life. - Oliver Burkeman

And here lies the essential difference between Stoicism and the modern-day 'cult of optimism.' For the Stoics, the ideal state of mind was tranquility, not the excitable cheer that positive thinkers usually seem to mean when they use the word, 'happiness.' And tranquility was to be achieved not by strenuously chasing after enjoyable experiences, but by cultivating a kind of calm indifference towards one's circumstances.

if you plan to spend some of your four thousand weeks doing what matters most to you, then at some point you're just going to have to start doing it.

The advice of etiquette experts on dealing with unwanted invitations, or overly demanding requests for favours, has always been the same: just say no. That may have been a useless mantra in the war on drugs, but in the war on relatives who want to stay for a fortnight, or colleagues trying to get you to do their work for them, the manners guru Emily Post's formulation – 'I'm afraid that won't be possible' – remains the gold standard. Excuses merely invite negotiation. The comic retort has its place (Peter Cook: 'Oh dear, I find I'm watching television that night'), and I'm fond of the tautological non-explanation ('I can't, because I'm unable to'). But these are variations on a theme. The best way to say no is to say no. Then shut up.
