There are many ways to take better pictures but one of my favorites to obey it the 'rule of thirds'.
Imagine your frame is divided into 3 equal sections both from left to right and top to bottom. Try to line up important elements in your frame with these imaginary lines. Place your horizon 2/3rds down the frame, or a building within a landscape off to the right, hitting the vertical third line. Even with a focal object being dissected by two lines.
Although this is called a 'rule', if you practice framing like this enough, in time your eye will learn when it's possible to push and even break this rule. Just have a play around.
