How are you getting on?
Recently I found myself greeting my colleagues with "How are you getting on?". In fact, in Russian it reads somewhat different. Literally "How is your progress?". And you know what? The most important thing about progress is the mere fact that there is progress!
I started asking this unconsciously, but now I do this intentionally. This way I show people that I do not question their success and only want to share it with me. This is just a quick status meeting with positive coloration.
