I'm sure you know people who act a certain way. Always stiff-necked, arrogant, and impatient. Quick to claim credit but slow to accept responsibility. Always ready to loudly boast about the things they think they've accomplished. Never willing to accept criticism. The very definition of mediocre.
I like to call them "Very Serious People."
"Very Serious People" are people like Michael Haigney, the 4Kids scriptwriter of Sonic X. Despite knowing absolutely nothing about Sonic or about anything related to Sega, he is quick to point out his non-existent contributions. And when challenged about his claims, simply dismisses them as the rantings of "a few fans," while at the same time never addressing any of them.
"Very Serious People" are people like Howard Wolfson, the Clinton campaign communications chief. Having never actually held elected office or been involved in a national campaign, he arrogantly dismissed Obama's chances early on. However, when it became clear his candidate was losing, he began a scurrilous charge to both nail down the idea of media sexism in the eyes of Clinton's white female supporters, while at the same time make racist overtones to voters in West Virginia and Kentucky. His candidate having lost, he still refuses to leave the scene, always making sure he stays in the headlines somehow.
"Very Serious People" are basically the entire crew of CNN. Despite all evidence that they have become miserably out of touch with the average viewer, and despite ratings showing them slipping to third place among the major demographics, they still refuse to change. Blissfully unaware they are, confident that their "seriousness" is what makes them better than "immature" Fox News or MSNBC.
This is a model of a person that you should never be. Be creative. Be willing to make yourself better. Accept criticism. But most importantly, don't start enjoying the smell of your own farts.
Lest you end up like the "Very Serious People."
