I worked with a dude who explained a chart he thought of for ranking people. Think of an x and y axis. The X axis is work ethic, the Y axis is smarts. Now think of four quadrants that creates.
Q1 - Top Left Corner - Smart, but Lazy
Q2 - Top Right Corner - Smart and Hard Working
Q3 - Bottom Right Corner - Dumb, but Hard Working
Q4 - Bottom Left Corner - Dumb and Lazy
In our line of work, you can't even get hired if you're dumb and lazy, so you don't see any of those people.
The Smart, but Lazy people - you can work with them. You just need to figure out how to motivate them. But they're not going to screw you up too badly other than a high risk of missed deadlines - but that can be resolved by putting some pressure on them.
The Smart and Hard Working people are obviously the best.
But the bottom right corner - the dumb, but hard working people. Those are the freaking worst. They're the ones that can screw things up by pushing terrible ideas, rubbing people the wrong way, making people want to quit, etc. Those are the folks you want to stay away from.
