happiness / luck
'das Glück' and 'der Segen' can both mean something very positive. 'Glück' is more general: it can be a feeling of great happiness or a lucky coincidence. 'Segen' is used figuratively when something is felt to be especially helpful, saving, or beneficial. It often sounds stronger than ordinary luck or happiness because it makes a burden easier to bear or clearly improves a situation. For example, you can say that a form of help is 'ein Segen' (a blessing). 'Glück' fits many pleasant or chance moments, while 'Segen' is more for something that truly does good and makes life easier.
