Nobody likes the “brilliant asshole”. Don’t be either of those things.
Doesn’t matter how much good work you do if you’re an insufferable jackass. You might be right or have good ideas but nobody’s going to want to work with you.
Doesn’t matter what you have to say or what you have to show for your efforts if people hate your guts. You might do something fantastic; doesn’t mean a damn thing if no one gets behind it.
Don’t be that guy.
