Attack and defence of middlegames

Some chess players are great attackers. These players excel in creating chaos on the board and slipping an attack under their opponents nose. This kind of player will take a trade of equal, or even lesser, value if it creates a break in their opponents defenses or if it just makes their opponent change plans.

Other players are great defenders. These players excel in maintaining a balanced board until their opponent makes a mistake, and then take full advantage of that mistake. When two players of this type face off it can indeed seem very boring.
If you feel that you tend to fall into this category, focusing on opening as many attacking lanes as possible while maintaining a solid defense until you see an opening is a good idea.
