Jim nailed it. Couldn't have said it better myself.

The "good" friction is beneficial: what do we do to get more of it?
|
To increase friction, we must change the shape of the two surfaces moving against each other in such a manner that creates traction. A good example of this would be sharp metal footpegs and soft rubber boots. Or sticky tires on dry pavement. Proper brake pad compound to encourage grip.

What do we do to reduce the "bad" friction?
|
To decrease [bad] friction we could introduce a lubricant. An example of this would be the grease contained in a bearing. Or the oil in your engine, suspension, or steering mechanisms.
