What is Right Action for a Buddhist regarding talking about personal success?

In this question a comment stated in part "The old sense of transferring merit had to do with mudita, you tell other people about your success so that other people can be happy about that. Being happy about other people success is meritable, so it works like transfer." The idea that telling people about your success is wholesome, is very surprising to me. I somehow had the impression that from a Buddhist point of view, being very modest and not making such things known was better. Did the Buddha teach anything specific about this? Thank you.
