What really pisses me off are people who must seek self validation constantly. If you continually have to say "I'm a pro" because of X. You're not a pro. You're a wannabe. It's just like Game of Thrones where having to say "I am the King" actually means you're not a true king.

Like if you post twenty minute videos of yourself doing a whole bunch of the same thing you're probably not doing anything truly worthwhile. For some of my friends with show reels they like to keep it to one song's duration with emphasis on their talents and highlights of their career, not continual day to day activities.
