The actual aim of showing off, if you think about it, is to convince people that you don’t need any more information.
I get it. We all want status and esteem. We all want people to respect and admire us. That desire is stronger in some than in others (much stronger), but at least a little bit we all want people to think we’re cool. So we show off, we flex, we strut.
In small doses, it’s fine. Be proud of your work, your accomplishments! Be happy to share with others, too.
But really, don’t try too hard to convince others that you’re done learning and improving. Because otherwise you might just be.
