Where people elsewhere talk about the heart (in the heart, from the heart, etc.), in Russia, you would more likely speak of the soul (душа). Русская душа is the famous Russian soul. One of the characteristics presented by Слот (or Slot): Сначала сделаем, а думать будем потом: first, act, then think. Живём один раз, а после нас хоть потоп: we live once, and after us, let the flood come.
