Luck is a knack for being in the right place at the right time. It does not imply any intrinsic superior worth or merit, but is a symptom of an upbeat personal energy. Other words for this or charm or charisma...a gift for making other people feel seen and heard. We see it right away with some people. It is temperamental or constitutional. It is an outlook shaped by the luck of possessing high levels animal vitality, which comes out to meet others with an inquiring outlook, regardless of, or notwithstanding any personal circumstances. Someone can still be lucky therefore, even if they are in other ways, unlucky.
Keats, lucky or unlucky? Unlucky, died far too young, and in great disappointment and sorrow, 'words writ on water'. Lucky, on the other hand, because he was much loved, died in the arms of friends and was posthumously published and now raised as a star in the firmament. The love of his friends brought him to publication. How many other writers, equally as marvellous, have escaped the attention of history? This of course, we shall never know.
Or else we could call it divine intervention. Il Matrimonio many years ago was in the army air corps for a while, had a helicopter tail rotor failure at 4000 ft which meant the pedals didn't work, that help you steer in for landing. The textbook said he should come back to a speed of 35 knots, makes pedals superfluous, turn off engine and drop vertically, but he thought eff that. I will be killed. Instead he came down very fast and low to take his chances near the ground. Was criticized for not using the protocol, but something in him over rode it. Maybe he would have been OK had he done it by the book, but his instinct said otherwise. The inner voice that some might call divine intervention. And who is to say it isn't that. The thing is, feeling confident to decide when to trust it.
Or fate. Yes indeed. Destiny. Berlioz's comment, his choice of word, a TALENT for luck, though, suggests some kind of synergy at work; a meeting point of fate with a person's positioning, calculations, or energy levels or energy field.
