> "Maybe you haven’t really trusted anyone with your wins yet"
At the end of one of her interviews on youtbue, Kelly McGonigal explains that -- paraphrased -- being praised to the face creates an intimate context around the praiser and the praisee, in which it's the praiser that sets the tone and initiates the dynamics. In a way, they find themselves in a position where they evaluate you. This is why taking praise gracefully is not trivial; people being praised usually show bodily signs of stress. It takes a real effort for the praisee not to dismiss or belittle their own achievement, just to get out of those dynamics as soon as possible.
At the end of said interview, the host praised Ms. McGonigal to her face. In response, she drew his attention to the fact that while he was talking, speaking those words of appreciation, she swallowed. The act of her swallowing was a kind of stress-relief (IIRC). (I'm sure we can all relate to choking up slightly when praised to the face.) She highlighted the dynamics of being praised to the face live, mid-interview, through her own reaction.
You may be avoiding sharing your wins with others because you instinctively might want to avoid the situation where others qualify you. In that situation, you experience being the subject of an evaluation, and that -- i.e., being talked about -- might feel like a subordinate position to be in, even if the judging is 100% positive. My remedy is to just yield, lean back, give in, permit the other person to be in control, allow them to have all power in that context, and just bask in the glorious warmth they're sending your way. It can be an experience that you remember for decades after, and you're going to start to crave it. (Peer recognition can be a huge motivator, i.e., doing things for recognition. Whether that's good or bad, is a separate topic :))
