I personally don't like bragging. If it come up in conversation about something I have done/accomplished in the past in the form of discussion, that is not bragging.
For me, the term "bragging" is usually someone trying to make others see them as outstanding.
Eg: when I met my now EX husband in college (senior year) he bragged about his high IQ & how smart he was IN HIGH SCHOOL while in college he barely got by. His bragging came across as arrogance. It was actually one of the red flags that made me want to cancel the wedding.
Just beware how you brag because it can be a real turn-off to some people rather than impress them
