+1. Some people act arrogant and feel like they know it all because they may have insecurity (in my local community: being out of job, failed startup, problems at home, etc). I recently met a couple of folks who were very content with themselves and very humble yet extremely smart. I almost forgot how much people like this can inspire me, discussions with them are very constructive and you feel really good after a conversation. Be content with yourself. If you're the person with the most knowledge and technical expertise then great, but be humble about other skills that you may not have and that you can still learn from others: teaching, inspiring, helping, making people feel that they're being listened to without being condescending.
