Bragging and ego tripping is completely different thing and I find it quite ugly
Everyone has an ego - it's sense of esteem or self, which in itself is not unhealthy. Even your judgement on other people's values comes from your own ego.
However, being negatively self-obsessed or self-deprecating can also be unhealthy, along with listening too much to the inner critic.
So many people are down on themselves I thought it would be fun for people to give themselves some praise - no matter what it might be, as everyone likes different things about themselves.
Don't take it so seriously - nobody is forcing you to take part, and you're totally welcome to get deeper and pull your ego apart in another thread.
